Awesome brain Flashcards
how many people in uk affected by neuro-disorder
1 in 6
what are neurons senstitive to
lack of oxygen and toxic aggregate proteins- mostly cant regenerate
what does grey matter do
processing
what is found in grey matter
neurons, synapses and processes
what does white matter do
communication
what is found in white matter
nerve fibres with myelin sheaths
what are the planes in the cns
sagittal, coronal, horizontal
what are the central nervous system directions
rostral caudal axis with ventral and dorsal
what is localisation of function
certain functions have certain locations
the regions communicate to work effectively (white matter important!!)
what is the internal capsule
a white matter bundle, connecting motor cortex with spinal cord.
Primary motor cortex sends white matter through the internal capsule, where most crosses the spinal cord.
two outcomes of stroke at the internal capsule
paralysis
rigid and hyperflex
outcomes of stroke with pure corticospinal tract lesion or small lesions in motor cortex
paralysis or flaccid
how do you treat stroke
CT- HEAMORRHAGE OR CLOT?
within 3-5 hours after symptoms
clot busters- tpa or tnk
thrombectomy
what is neurplasticity
when nervous system can be modified by experience, behaviour or neural changes
changing connections and the strength of connections
stronger/ weaker or more/ less synapses
what is functional plasticity
repurposing neurons after gross injury or loss of brain tissue early in life
