Editor's Notes
- #1 Hello
- #9 primary somatosensory cortex (S1) is responsible for processing somatic sensations like touch, pain, temperature, and proprioception (body position). It receives sensory input from the thalamus and has a somatotopic organization, meaning different areas of the cortex correspond to specific body parts,
- #13 Brodmann area 7 (BA7) is a region of the posterior parietal cortex involved in the integration of sensory and motor information, particularly for visuomotor coordination, such as reaching and grasping. parietal lobe lesion include problems with spatial awareness, language, and sensation, such as difficulty navigating, writing (agraphia), reading (alexia), or performing math (acalculia). Other symptoms can include numbness, tingling, weakness on one side of the body, or a neglect of one side of space.
- #14 Brodmann areas 5 and 7 are located in the somatosensory association cortex and are responsible for integrating sensory and motor information to form conscious representations of the body and its surroundings
- #15 superior colliculus is a paired structure in the midbrain that plays a key role in visual attention and the control of eye and head movements, helping the brain to orient toward environmental stimuli. lateral geniculate body (LGB), also known as the lateral geniculate nucleus (LGN), is a key structure in the thalamus and the visual pathway that relays visual information from the retina to the primary visual cortex.
- #17 Corticobasal syndrome (CBS) is a rare, progressive neurological disorder caused by the abnormal clumping of a protein called tau in the brain's cortex and basal ganglia. It is characterized by a combination of movement disorders like rigidity, tremor, and apraxia (inability to perform purposeful movements), as well as cognitive and language deficits. Asomatognosia is a specific type of somatosensory neglect where a patient might deny their own limb belongs to them, whereas anosognosia is a broader lack of insight into any deficit, such as paralysis. Balint's syndrome This is a rare and disabling disorder caused by bilateral damage to the posterior parietal lobe. It is defined by a triad of symptoms: Optic ataxia,occulomotor apraxia,simulatogonsia. Gerstmann's syndrome Resulting from damage to the angular gyrus in the dominant (usually left) parietal lobe, this syndrome affects several learned skills, some of which have visual components. Auditory neglect is a neurological disorder where a person fails to attend to sounds on one side of space, most commonly the left side, due to a brain injury, typically in the right hemisphere
