What happens if the thalamus is damaged

This article will outline the effects of damage to different areas of the brain. Damage to the parietal lobe can result in: Difficulty locating words when writing; Difficulty reading; Difficulty drawing objects; Difficulty with differentiating between left and right; Difficulty with mathematics; Loss of spatial awareness and awareness of certain body parts; Difficulties with hand and eye coordination; and Visual field deficits.

QLD DoH Occipital Lobe The occipital lobe is primarily responsible for visual processing and perception and receives visual data from the retina. Damage to the occipital lobe can result in: Visual field deficits; Difficulty with locating objects in the visual field; Visual hallucinations; Word blindness the inability to recognise words ; and Difficulties with reading, writing, recognising objects and distinguishing colours.

Thalamus and Hypothalamus The thalamus receives sensory information from all of the sensory systems except smell and passes it on to the relevant primary cortical area. The hypothalamus has many functions, including: Linking the nervous system to the endocrine system; Temperature regulation; Controlling appetite; Releasing hormones; Maintaining daily physiological cycles; Regulating fluid balance; Regulating blood pressure; Regulating the autonomic nervous system; Managing sexual behaviour; Regulating emotional responses.

The thalamo cortical connections are bidirectional; they lead from the thalamus to the cortex and from the cortex back to the thalamus. This is called Thalamo-cortico-thalame circuit. The result of this is that small thalamus injury may "mimic" cortex syndromes. In some syndromes the specialization of the brain hemisphere can be recognized. Inability to inculcate information anterograde amnesia.

Large bilateral medial thalamic lesions including the intralaminar nuclei. Hemiplegic motor neglect, temporary lack of movement without power loss. Visual somatosensory and nociceptive cores contralateral.
