Cerebral Cortex Flashcards
1
Q
Allocortex
A
3 layered cortex that contains tge paleocortex and hippocampus.
2
Q
What sensation is the paleocortex involved in?
A
Olfaction
3
Q
Neurons of layer four which are excitatory and use glutamate as neurotransmitter
A
Spiny stelate cells.
4
Q
Has “apical tufts” and cell bodies in layers: 2/3, 5, & 6.
A
Pyramidal neurons
5
Q
Act as coincidence sensors between cortical and sensory input.
A
Pyramidal neurons
6
Q
Present in all neocortical layers, inhibitory GABA.
A
Non - pyramidal inhibitory neurons
7
Q
What cells are responsible for the majority of cortical input?
A
Pyramidal cells.
8
Q
Excitotoxicity
A
Too much stimulation can damage neurons.
9
Q
3 ways to protect against excitotoxicity.
A
- Enhancing inhibition.
- Limiting Action Potentials.
- Blocking excitation.
