Unit 1 - LAA - Neuroanatomy Flashcards
What kind of awareness does the brain provide?
conscious
The brain is involved in what kind of processes?
internal mental processes - thoughts
What type of neurons is the brain made up of a vast number of?
Interconnected neurons
What is the brain separated into?
two hemispheres
What are the two half of the brain referred to as?
Hemispheres
Where does the brain receive info from and why?
From various sensory organs to give information about the body
What is meant by localisation of function?
Specific areas of the brain have specific jobs/functions
What is meant by lateralisation of function?
Brain is split into two halves, left and right. Each hemisphere has a different function.
What is the corpus collosum?
collection of nerve cells that connects the two hemispheres
What does the spinal cord do?
Connects the brain via the brain stem to the rest of the body and transfers messages between them
What is meant by plasticity?
The brain is ‘flexible’ enough to change and adapt as a result of new experiences, learning or brain damage throughout our lives. This involves the growth of new connections (synapses).
What is synaptic pruning?
Where as neurons develop we build synaptic connections. As we get older these connections are either deleted or strengthened to take on new demands
Why is the biological approach reductionist?
reductionist
Which hemisphere in the brain is responsible for what function?
Left for language, Right for recognition.
