What is the premotor cortex responsible for?

The premotor cortex, which is located just anterior to the primary motor cortex, is involved in planning and organizing movements and actions. Neuronal activity in prefrontal and premotor areas precedes activation of the primary motor cortex and neurons in the spinal cord.

What would happen if your prefrontal cortex was damaged?

A person with damage to the prefrontal cortex might have blunted emotional responses, for instance. They might even become more aggressive and irritable, and struggle to initiate activities. Finally, they might perform poorly on tasks that require long-term planning and impulse inhibition.

What indicates damage to the primary motor area?

Decreased Motor Control When an injury damages the primary motor cortex, the person will typically experience a loss of coordination and poor dexterity. For example, the person usually loses the ability to perform fine motor movements that involve the muscles of the hands, fingers, and wrists.

What is the primary motor cortex responsible for MCQ?

1. Primary motor area:– it lies in the frontal lobe anterior to the central sulcus. they control the skeletal muscle activity.

What happens if you damage your parietal lobe?

Damage to the front part of the parietal lobe on one side causes numbness and impairs sensation on the opposite side of the body. Affected people have difficulty identifying a sensation’s location and type (pain, heat, cold, or vibration).

What happens in the prefrontal cortex?

The prefrontal cortex (PFC) plays a central role in cognitive control functions, and dopamine in the PFC modulates cognitive control, thereby influencing attention, impulse inhibition, prospective memory, and cognitive flexibility.

Can humans survive without a brain?

Since it controls vital functions such as breathing, swallowing, digestion, eye movement and heartbeat, there can be no life without it. But the rest of the brain is obviously capable of some remarkable feats, with one part able to compensate for deficiencies in another.

What causes damage to the prefrontal cortex?

Damage to the frontal lobes can affect one or more of the functions of this area of your brain. An injury, stroke, infection, or neurodegenerative disease most often causes damage to the frontal lobes.

How is the motor cortex damaged?

If someone suffers a stroke, for instance, that causes damage to the primary motor cortex on one side of their brain, they will develop an impaired ability to move on the opposite side of their body.

What happens if the auditory cortex is damaged?

Damage to the auditory cortex can disrupt various facets of auditory perception. For example, damage (e.g., like that caused by a stroke) might cause deficits in the ability to detect changes in pitch, localize sounds in space, or understand speech.

Which is the largest part of the brain Mcq?

Cerebrum is the largest part of the brain.
