What happens if the neocortex is damaged?
Damage to the neocortex of the anterolateral temporal lobe results in semantic dementia, which is the loss of memory of factual information (semantic memories). These symptoms can also be replicated by transcranial magnetic stimulation of this area.
What would happen if the motor cortex was damaged?
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 happens when you damage your parietal lobe?
Like all strokes, a parietal lobe stroke involves either the rupture or blockage of a blood vessel in the brain. It’s the resulting lack of constant blood flow to the parietal lobe that deprives that area of adequate oxygen and causes cell death that impairs many sensory, visual, and/or language functions—sometimes permanently.
What would happen if the parietal lobe was damaged?
Damage to the right parietal lobe can result in neglecting part of the body or space (contralateral neglect), which can impair many self-care skills such as dressing and washing. Right side damage can also cause difficulty in making things (constructional apraxia ), denial of deficits (anosagnosia) and drawing ability.
What are symptoms of parietal lobe injury?
Left-Right Confusion. Since parietal lobe damage results in problems with perception,it can sometimes lead to people losing the ability to tell their right from left.
What are the symptoms of left parietal lobe?
Damage to the left parietal lobe can result in what is called “Gerstmann’s Syndrome.”. It includes right-left confusion, difficulty with writing (agraphia) and difficulty with mathematics (acalculia). It can also produce disorders of language (aphasia) and the inability to perceive objects normally (agnosia).
