Golgi neurons
type I: pyramidal cells with long axons which leave gray matter of CNS
type II: stellate neurons with short axons
t or f important neurons for survival have unusually large axons
t
Why are neuromuscular junctions such reliable synapses?
Because the axon terminal is large and the presynaptic terminal contains a large number of active zones
fxn of acetylcholinesterase
break down ACh
why are NMJs more easily excited
larger number of synaptic vesicles releasing NTs
where do somatic sensory axons enter spinal cord
dorsal roots (bc u feel like a dolphin)
most of the eyes refractive power is accomplished by
cornea
visible light spectrum
400-700nm
binocular visual field
part of visual field you can see with both eyes
what is used to represent low and high frequencies
phase locking for low, tonotopy for high
which area is primary motor cortex
area 4
fxn of deep cerebellar nuclei
relay info from cerebellum to various brain stem structures
- Which of the following structures are included in the motor loop through the cerebellum? Choose the correct option.
Sensory input through pontine nuclei to cerebellum to motor cortex through the
ventral lateral nucleus of the thalamus
What led to the belief that anterior thalamus plays an important role in emotion?
The observation that lesions in the anterior thalamus led to spontaneous laughing
and crying
