These deep structures in the thalamus
and brainstem help our visual cortex to filter important information from the flood of visual input even before we consciously perceive it,' added Michael Skeide, scientific researcher at the Max Planck Institute for Human Cognitive and Brain Sciences.
The research team thinks that the thalamus
is the coordinator of long-term memory consolidation, the process where recently acquired information is transferred from the hippocampus to the cortex to be filed away as long-term memory.
Our approach directly targets the thalamus
but is noninvasive.
Until now, the only way to achieve this was a risky surgical procedure known as deep brain stimulation, in which electrodes are implanted directly inside the thalamus
These results demonstrate that metabolic changes occur in the thalamus
during HDT in rhesus monkeys.
By utilizing MI and PCMI to analyze the LFPs recorded from the hippocampus and the thalamus
, the interactions between them in the termination of seizures can be investigated.
In highlighting damage to the pathways that physically connect the thalamus
, one of the hubs of consciousness if you will, and the motor cortex, which drives our voluntary muscular activity, as the reason behind the dissociation we have provided an important explanation".
Recent studies have shown that the corticothalamic projection in the primary sensory neocortical area to the corresponding sub-nuclei of the thalamus
directly results in the coordination and precision in the firing of thalamic neurons from these sub-nuclei to the neocortex (Andolina, Jones, Wang & Sillito, 2007; Worgotter, Eyding, Macklis & Funke, 2002; Sillito, Jones, Gerstein & Wet, 1994).
INTRODUCTION: Occlusion of percheron artery giving rise to bilateral thalamic infarct represents a rare presentation of stroke which accounts for 11% of all vertebrobasilar infarcts (1) although infarcts restricted to thalamus
were reported for the first time more than 100 years ago by Dejerine and Roussy.
In the intact (whole) mouse brain, for instance, structures as deep as thalamus
and hypothalamus 8 mm beneath the surface can be imaged-a longstanding goal in neurobiology.
receives blood from both the anterior and posterior systems to varying degrees.
13] We used the region of interest method to evaluate FDG uptake in brain regions with significant metabolic changes, including the thalamus
They compared the hippocampus, which is known to be damaged early in the disease, and the thalamus
, an area that is generally not affected until the late stages.
Blood flow was reduced in the thalamus
in response to fructose, but also in entirely different regions: the hippocampus, posterior cingulate cortex, fusiform and visual cortex.
Glucose resulted in a significantly greater reduction in hypothalamic CBF compared to fructose and it increased functional connectivity between this part of the brain and the thalamus
