The thalamus is believed to play crucial role in processing viscero-sensory information, and regulating the activity of amygdala in patients with panic disorder PD. Previous functional neuroimaging studies have detected abnormal activation in the thalamus in patients with PD compared with healthy control subjects HC. Very few studies, however, have investigated for volumetric abnormalities in the thalamus in patients with PD. Furthermore, to the best of our knowledge, no previous study has investigated for shape abnormalities in the thalamus in patients with PD.

A seven-year-old Australian boy who is missing most of his visual cortex has surprised doctors by being able to see well enough to recognise faces and play soccer - the first known case of its kind. In spite of suffering a significant brain injury when he was a newborn, the biggest problem the boy, referred to only as "B. Speaking at a neuroscience conference in Sydney this week, researchers from the Australian Regenerative Medicine Institute at Monash University presented B. The visual cortex is a region of the wrinkled, outer part of the brain at the back of your head responsible for sorting information from the retina into a personal picture show. To be more precise, the retina sends messages down the optic nerve to a relay centre in the thalamus called the inferior pulvinar , which helps control and focus the eyes based on the objects in the line of sight. From there the information goes to a part of the visual cortex called visual area 1 V1.
Novel cognitive insights from the first year after bi-thalamic infarct
This 3D view shows a composite of the thalamus of healthy controls outlined in red and MS patients magenta. The whole thalamus is generally smaller in MS due to atrophy, and is also shifted as seen in blue slightly beyond the position of the normal thalamus due to atrophy of other parts of the brain. Release Date: March 21, The location of the thalamus in the brain, its unique function and its vulnerability to changes wrought by the disease make the thalamus a critical barometer of the damage that MS causes to the brain. At the annual meeting of the American Academy of Neurology today, Zivadinov will discuss a study he performed in collaboration with colleagues from Charles University in Prague.
A Toronto man is only the second known person to have acquired synesthesia as a result of a brain injury, in this case a stroke. About nine months after suffering a stroke, the patient noticed that words written in a certain shade of blue evoked a strong feeling of disgust. Yellow was only slightly better. Raspberries, which he never used to eat very often, now tasted like blue -- and blue tasted like raspberries. High-pitched brass instruments -- specifically the brass theme from James Bond movies -- elicited feelings of ecstasy and light blue flashes in his peripheral vision and caused large parts of his brain to light up on an MRI.
