Motor and Premotor Cortex

Motor and Premotor Cortex

To the tune of “Justified” by Kacey Musgraves

[Verse 1]
Primary motor cortex
Area 4, functions in
Fine movements and motor strength
And movement direction

[Pre-Chorus]
Damage to this, the precentral gyrus
Causes loss of fine movements, speed, and strength

[Chorus]
Primary motor cortex
Has neurons that project
To the spinal and the
Cranial nerves
Along with the
Basal ganglia and
The red nucleus
Both regions that control movement
Mmm mmm mmm, mmm mmm mmm
Both regions that control movement

[Verse 2]
Pre motor areas
6, 8, and 44
Lateral 6 is premotor
Area 8, the frontal eye field

[Pre-Chorus]
Damage to this, the premotor cortex
Causes loss of movement programming

[Chorus]
Premotor cortex
Has neurons that project
To the spinal cord and the
Motor cortex
It receives projections
From different regions
Like the parietal areas
And the dorsolateral prefrontal area
Mmm mmm mmm, mmm mmm mmm
And the dorsolateral prefrontal area

[Bridge]
The eye fields receive
Projections from the
Superior colliculus
And PG
Damage to this region
Causes changes in
Voluntary gaze
And behaviours

[Chorus]
Pre motor area’s function
Includes the decision
Of what information
The frontal lobe receives
And corollary discharge
And motor strength at large
The mirror neuron system
In addition to eye movement
Mmm mmm mmm, mmm mmm mmm
In addition to eye movement
