Neurophysiology — Flashcards

Flashcard 41: Long-term _____ is classically seen in the cerebellum

Answer: depression

Flashcard 42: _____ binding to the NMDA receptor is essential for the receptor to respond to glutamate

Answer: Glycine

Flashcard 43: What is the function of the **Anterior thalamic nuclei**? _____

Answer: Memory and emotion (part of the Papez circuit)

Extra: The anterior thalamic nuclei are a key component of the limbic system and the Papez circuit. They receive input from the mammillary bodies (via the mammillothalamic tract) and project to the cingulate gyrus. In contrast, alertness and arousal are functions primarily associated with the **intralaminar nuclei** of the thalamus (as part of the reticular activating system).

Flashcard 44: Medial motor pathways:_____ reticular nuclei transmit excitatory signals to the axial muscles of the vertebral column and extensor muscles of limbs by way of the pontine reticulospinal tract, located in the anterior column of the cord.

Answer: Pontine

Flashcard 45: Transcutaneous electrical nerve stimulation acts by inhibition at the _____synaptic level in the dorsal horn

Answer: pre

Flashcard 46: Dopamine inhibits the _____ basal ganglia pathway through D2 receptors

Answer: indirect

Flashcard 47: If venous pressure exceeds CSF pressure, arachnoid villi _____ the tubules to prevent the entry of blood into the subarachnoid space.

Answer: close

Flashcard 48: One control center for horizontal gaze is located in the _____, which is responsible for contra-lateral gaze

Answer: frontal eye field

Flashcard 49: _____ neurons within the striatum stimulate the indirect basal ganglia pathway

Answer: Cholinergic

Flashcard 50: In decorticate rigidity, the lower limbs show _____ due to loss of corticoreticular excitation of the inhibitory reticular formation of the medulla.

Answer: extension
