Stuff I didn't have on my flashcards
more intense stimulus needs
- faster neuron firing
- multiple neurons firing at once
catecholamines
reward system
- dopamine
- serotonin
- epinephrine + norepinephrine
GABA what does it do
reduces neuron excitability by inhibiting nerve transmission
impramine
- MAO inhibitor
serotonin uptake
reserpine
decreases neurotransmitter release
neuroleptics
- decreases dopamine receptors
treat schizos
amphetamine
- increases neural transmission
. targets reward system (dopamine +norepinephrine) - euphoria, fast brain + strength
types of glia
- astrocytes
- olygodendrocytes
- microglia
- ependymal cells
astrocytes
supply nutrients + oxygen to neurons
olygodendrocytes
myelin
microglia
destroy pathogens + remove dead neurons
ependymal cells
- produce cerebrospinalfluid
- neurogeneration
somatic nervous system
voluntary movement, in PNS
3 midbrain parts
- tectum
- tegmentum
- peduncles
tectum role
- respond visual/auditory stimuli
- coordinates head + eye movement
tegmentum role
- homeostasis
- reflex
peduncles functions
- attach cerebrum to brainstem
- balance + posture
- motor skills + movement
mediodorsalis location
nucleus in thalamus
mediodorsal function+ afferents & efferents
- behaviour + intellect
- afferents; thalamus, hypothalamus, amygdala
- efferent; prefrontal cortex
basal ganglia location+ connection
base of forebrain top of midbrain
- connected to; thalamus, cerebral cortex + brainstem
basal ganglia function
- control voluntary movement
- learning
- eye movement
- cognition
thalamus functions
- integrates impulses from cerebellum + basal ganglia to motor centre
- relays sensory impulses to sensory cortex
- mediodorsal nucleus projects to prefrontal cortex
- ascending reticular actuating system
insula regions
- sensorimotor
- central-olfactogustatory
- socio-emotional
- cog
