The Biological Bases Of Behaviour Flashcards
What are the 2 bio bases of behaviour?
Dualism and materialism
What is Dualism?
Rene Descartes said that the mind and the body are two different entities that only communicate through a small portion in the brain. Both make a person
What is materialism?
Everything is composed of physical matter even our mind and what we think and do results from matter and it’s movement
The nervous system is composed of?
CNS, PNS
central nervous system and the peripheral nervous system
What is the CNS?
Brain and spinal cord
What is the PNS?
Nerves outside CNS parts and it is the communication path between CNS and externalities
The brain is protected by?
Meninges and cerebrospinal fluid
The spinal cord…
Connects the brain to the rest of the body
Nerves are actually..
Bundles of axons that’s transport electrochemical impulses
Neurotransmitters are..
Chemical substances that’s are sent from neuron to neuron (released when an impulse is made by diffusing across the synapse)
How does the communication from neuron to neuron work?
Dendrites receive neurotransmitters which pass through the soma who then go into the axon which is protected by the myelin sheath and then go to the axon terminals. The neurotransmitters then jump across the synapse to another neuron
The post synaptic potential is composed of ..
Voltage change at the receptor site
What is affected by the voltage chg at receptor site?
The probability of the postsynaptic neuron firing
What is a + voltage shift?
..-v.shift?
Excitatory PSP
Inhibitory PSp
What are neural impulses?
Interconnected neurons that fire together or sequentially.
