Recording from downstream neurons in the caudate and
from thalamic neurons projecting to the medial frontal cortex indicated that this phenomenon originates within cortical networks.
Not exact matches
However, while the maps for visual space and eye input were thought to originate
from the segregation of
thalamic afferents in visual cortex, the origin of the other maps remained unclear.
The work of Kremkow and colleagues indicates that the organization of all maps originates
from the same principle: an arrangement of
thalamic afferents that minimizes differences in spatial position, eye input and light / dark polarity among neighboring cortical neurons.
Spindles come
from a structure of the brain called
thalamic reticular nucleus and spike around 7 - 15 per second.
«Often during the night a regular pattern is manifested, where a slow oscillation
from the cortex is immediately followed by a
thalamic spindle and while this happens, a hippocampal ripple appears in parallel.
Previous studies suggested that stimulation of
thalamic neurons may awaken patients who have suffered a traumatic brain injury
from minimally conscious states.
Housed in a brain region called the thalamus, a group of brain cells called the
thalamic reticular nucleus, or TRN, had been suspected to control the brain's ability to pay selective attention to cues
from the outside world.
Co-localization of anterograde tracer
from the eye and retrograde tracer
from Cluster N was observed in lateral and ventral parts of the DLL, the LdOPT and the SpRt of the
thalamic Gld.
D: Confocal 3D - stacks in the
thalamic Gld at high magnification indicate direct contact (arrows) between retinofugal fibers (shown in red) and somata / proximal dendrites retrogradely labeled
from Cluster N (shown in green).
