Frontal Lobe:
- Removal: Results in personality changes, reduced impulse control, difficulty with problem-solving, and decision-making.
- Consequences: Impaired social interactions, disinhibition, and reduced executive functioning.
Parietal Lobe:
- Removal: Causes difficulty in perceiving and interpreting spatial information, such as location and shape.
- Consequences: Impaired depth perception, apraxia (difficulty performing skilled movements), and anosognosia (denial of deficits).
Temporal Lobe:
- Removal: Affects memory, language comprehension, and auditory processing.
- Consequences: Amnesia, aphasia (language disorders), and difficulties with complex auditory tasks.
Occipital Lobe:
- Removal: Leads to blindness or severe visual impairments in the corresponding visual field.
- Consequences: Loss of vision, difficulty navigating, and impaired object recognition.
Cerebellum:
- Removal: Affects balance, coordination, and motor skills.
- Consequences: Ataxia (difficulty with balance and walking), tremors, and dystonia (involuntary muscle contractions).
Hippocampus:
- Removal: Impairs memory formation, particularly episodic memory (events and experiences).
- Consequences: Severe amnesia, difficulty learning new information, and disorientation.
Thalamus:
- Removal: Affects consciousness, arousal, and sensory processing.
- Consequences: Persistent vegetative state, coma, or severely impaired consciousness.
Brainstem:
- Removal: Essential for survival, controls vital functions such as breathing, heart rate, and body temperature.
- Consequences: Immediate death or severe impairments in all body functions.
It is important to note that:
- These are general effects, and the specific consequences can vary depending on the individual and the extent of the damage.
- Removing one part of the brain does not entirely eliminate its functions, as other brain areas may compensate to some extent.
- The effects of brain damage can be permanent or partially reversible, depending on the severity and location of the injury.
