Neuromodulation Flashcards
Definition of Neural plasticity.
Neural plasticity = neurones change their structure, function and organisation in response to experience.
The changes include strengthening or weakening nerve connections or adding new nerve cells.
How do neurones change in neural plasticity?
Neural plasticity = neurones structure, function and organisation changes in response to experiences. the changes of nerve cells include adding new nerve cells or strengthening or weakening nerve connections.
Describe neural plasticity as a whole.
Neural plasticity is when neurones change their structure, function and organisation in response to experience. The changes of nerve cells include strengthening or weakening nerve connections and adding new nerve cells.
What are the changes like in neural plasticity?
Neural plasticity is when neurones change structure, function and organisation in response to experiences. The changes include adding new nerve cells and strengthening and weakening nerve connections.
What do similar neurones do?
Neural plasticity is when neurones change structure, function and organisation due to experiences. The changes of nerve cells in neural plasticity include adding new nerve cells or strengthening or weakening of Nerve connections. Neurones that fire together, wire together. So neurones that have a similar structure, wire together
Definition of potentiation.
Potentiation is an increase in information flow.
Depression is a decrease in information.
Definition of depression.
Depression = is a decrease in information. Potentiation = is an increase in information flow.
What is the difference between potentiation and depression?
The difference between potentiation and depression is that depression is a decrease in information and potentiation is an increase in information flow.
Where does neural plasticity occur?
Neural plasticity is when neurones change structure, function and organisation in response to experience. The changes to nerve cells include adding new nerve cells and strengthening or weakening nerve connections. Neurones that fire together, wire together. potentiation is an increase in information flow and depression is a decrease in information.
Neural plasticity can occur at synapses and it is called synaptic neural plasticity.
Definition of synaptic Neural plasticity?
Neural plasticity is when neurones change structure, function and organisation in response to new experience. The changes of nerve cells include adding new nerve cells or strengthening or weakening nerve connections. Neurones that fire together, wire together. Potentiation is an increase in information flow and depression is a decrease in information. Neural plasticity can occur at synapses, this is called synaptic neural plasticity.
Synaptic Neural Plasticity = is when neural plasticity occurs at synapses. Neural plasticity is a change of structure, function and organisation in neurones due to new experience. The changes include adding new nerve cells or strengthening or weakening nerve connections.
Can we improve behaviour and cognitive functions?
We change improve behaviour and cognitive function because the brain can adapt and change to changes in the environment. Without the ability of the brain being able to adapt, we would not be able to create, learn or consolidate memories and a person who has suffered a stroke would not be able to rehabilitate.
Why is it important that the brain can adapt/changes to changes in the environment?
We can improve behaviour and cognitive function because the brain can change and adapt to changes in the environment. Without the ability of the brain being able to change or adapt to changes in the environment, we would not be able to create, learn or consolidate memories and a person who has had a stroke would not be able to rehabilitate.
If the brain was not able to adapt to changes In the environment what would that mean?
The brain can adapt and change in response to changes in the environment. Without this ability:
- we wouldn’t be able to create, learn or consolidate memories.
- a person who has had a stroke would not be able to rehabilitate.
We can improve behaviour and cognitive function because the brain can adapt and change to changes in the environment.
What can the brain do that is important in terms of the environment?
The brain can adapt and change to changes in the environment. This is important because if the brain was not able to adaptively change to changes in the environment, we would not be able to create, learn or consolidate memories and a person who has had a stroke would not be able to rehabilitate.
How can you enhance brain function?
You can enhance brain function by brain stimulation. The two types of brain stimulation include TMS which is transcranial magnetic stimulation and tDCS which is Transcranail direct current stimulation.
What does TMS stand for?
TMS stands for transcranial magnetic stimulation. TMS is a type of supra threshold stimulation which causes neurones to fire. Supra-threshold stimulation causes neural depolarisation which means it causes action potentials or neurones to fire. Transcranial magnetic stimulation is a type of supra-threshold stimulation so TMS causes neural depolarisation and causes neurons to fire (action potentials). Transcranial magnetic stimulation is safe and non-invasive brain stimulation tool and it is a type of supra-threshold stimulation which causes neurones to fire (action potential) or neural depolarisation. TMS research is interested in how excitably an area of the brain is when performing a task.
Definition of TMS.
TMS is transcranial magnetic stimulation, it is a safe and non-invasive brain stimulation method. Transcranial magnetic stimulation is a type of supra-threshold stimulation which causes neurons to fire. TMS is a type of supra-threshold stimulation which causes neural depolarisation which means it causes action potentials or neurones to fire. Transcranial magnetic stimulation is interested in how excitably an area of the brain is when performing a task.
why is transcranial magnetic stimulation good?
Transcranial magnetic stimulation is good because it is safe and non-invasive. Transcranial magnetic stimulation is a type of supra-threshold stimulation which means it causes neurones to fire (action potentials). So TMS is a type of supra-threshold stimulation which causes neural depolarisation which means it causes action potentials or neurons to fire. Transcranial magnetic stimulation is interested in how excitably an area of the brain is when performing a task.
What is TMS a type of?
TMS or transcanial magnetic stimulation is a non-invasive and safe brain stimulation tool. Transcranial magnetic stimulation is a type of supra-threshold stimulation which means it causes neural stimulation so in order words it causes neurones to fire (action potentials). TMS research is interested in how excitably an area of the brain is when performing a task.
What does transcranial magnetic stimulation cause and why?
TMS or transcranial magnetic stimulation causes neurones to fire which is called neural depolarisation. Another word for neurones to fire is action potential so TMS drives action potentials. Transcranial Magnetic stimulation causes neurones to fire because TMS is a type of supra-threshold stimulation which means it causes neurones to fire.
Transcranial Magnetic stimulation = is a type of supra-threshold stimulation which causes neurones to fire.
Definition of supra-threshold stimulation.
Supra-Threshold stimulation = causes neurones to fire or causes neural depolarisation. Transcranial magnetic stimulation is a type of supra-threshold stimulation which means TMS causes neural depolarisation or causes neurones to fire (action potential).
What does supra-threshold stimulation cause?
Transcranial magnetic stimulation is a type of supra-threshold stimulation which causes neurones to fire. TMS causes neural depolarisation which means it drives action potentials. Transcranial magnetic stimulation is a safe and non-invasive brain stimulation tool.
Definition of neuronal depolarisation.
Neural depolarisation = causes neurones to fire. Transcranial magnetic stimulation is a type of supra-threshold stimulation which means it causes neural depolarisation or in other words causes neurones to fire (action potentials).
What is another word for a Neuron firing?
Another word for neurones firing is action potential. TMS or transcranial magnetic stimulation causes neurones to fire or causes neural depolarisation. This is because Transcranial magnetic stimulation is a type of supra-threshold stimulation which causes neurones to fire or drives action potentials. TMS only works if you apply the coil right above the primary motor cortex and occipital cortex.
How does Transcranial magnetic stimulation work?
If you put a coil near an electric current it generates a magnetic field. So, if you put a coil that has an electric current inside of it near the scalp it creates magnetic fields perpendicular to the coil so at right angles to the coil. This causes brain to have electric currents as the brain as wet stuff that is very conductive. Transcranial magnetic stimulation relies on electromagnetic induction, it uses a coil that has a current inside and places it near the scalp which generates an electric currents in the brain because there are wet stuff in the brain that is very conductive.
Where do you place the coil?
You place the coil near the scalp because the brain has wet stuff that is very conductive. So when you place a coil that has an electric current in it, it generates an electric current in the brain. This is because coil generates a magnetic field perpendicular to the coil so at right angles which generates a current in the brain as there are very conductive areas in the brain. TMS only works if you apply coil directly above primary motor cortex and occipital cortex.
What happens if you put a coil near the scalp?
If you put a coil that has an electric current in it near the scalp it generates electric current in the brain because if you put a coil near an electric current it generates a magnetic field. So if you place a coil near the scalp it generates a magnetic field perpendicular to the coil so at right angles to the scalp which causes currents in the brain because the brain has wet stuff that is very conductive. TMS only works if you apply the coil right above the primary motor cortex and occipital cortex.
