Which deep structure is responsible for reading out?
Basal ganglia
2 of 17
The cortex and caudate and putamen share?
Excitatory connections
3 of 17
The globus pallidus/substantia nigra and caudate and putamen share?
Inhibitory connections
4 of 17
The thalamus and cortex share?
Excitatory connections
5 of 17
The subthalamic nucleus and globus pallidus/substantia nigra share?
Both excitatory and inhibitory connections
6 of 17
What is found within the substantia nigra?
Melanin
7 of 17
What connection type does glutamate facilitate?
Excitatory connections
8 of 17
What connection type does GABA facilitate?
Inhibitory connections
9 of 17
What connection type does dopamine facilitate?
Modulatory connections
10 of 17
In the direct pathway of timing and movements, which structure is effected by the substantia-nigra/globus pallidus?
Thalamus (stimulated)
11 of 17
In the indirect pathway of timing and movements, what is inhibited less causing more stimulation of the substantia-nigra/globus pallidus resulting in no movement?
Subthalamic nuclei
12 of 17
Which pathway favours D1 receptors and why?
Direct pathway. D1 receptors are excited by dopamine
13 of 17
Which pathway favours D2 receptors and why?
Indirect pathway. D2 receptors are inhibited by dopamine
14 of 17
What is the cerebellum involved in?
Acquisition and control of skilled movements
15 of 17
What is the stretch reflex?
Gravity acts on a muscle. Receptors output to spinal cord to say muscle has been stretched. Loop back to muscle, gravity effects counteracted.
16 of 17
What test is the stretch reflex observed in?
The hammer-knee test
