The thalamus has multiple functions, and is generally believed to act as a relay station, or hub, relaying information between different subcortical areas and the cerebral cortex. [29] In particular, every sensory system (with the exception of the olfactory system ) includes a thalamic nucleus that receives sensory signals and sends them to the ...
The thalamic region of the brain. The main concepts of the Cannon–Bard theory are that emotional expression results from the function of hypothalamic structures, and emotional feeling results from stimulations of the dorsal thalamus. The physiological changes and subjective feeling of an emotion in response to a stimulus are separate and ...
Thalamencephalon (Latin: thalamencephalon), also called thalamic region (regio thalamica) or thalamic complex (complex thalamica) is a complex structure comprising thalamus (in the wider sense of the term thalamus, i.e. dorsal thalamus, or thalamus proper, plus subthalamus, or ventral thalamus) and several adjacent structures: epithalamus and metathalamus.

Such studies were followed by Ranulfo Romo in the somatic sensory system, to confirm, using a different percept and brain area, that a small number of neurons in one brain area underlie perceptual decisions. Other lab groups have followed Mountcastle's seminal work relating cognitive variables to neuronal activity with more complex cognitive tasks.
Much of the brain activity in sleep has been attributed to the thalamus and it appears that the thalamus may play a critical role in SWS. The two primary oscillations in slow wave sleep , delta and the slow oscillation, can be generated by both the thalamus and the cortex.
The thalamic fasciculus is a component of the subthalamus (ventral thalamus). It is synonymous with field H 1 of Forel.Fibers from the lenticular fasciculus (field H 2 of Forel), are joined by fibers from the ansa lenticularis – different parts of the internal globus pallidus, before they enter the ventral anterior nucleus of the thalamus to form the thalamic fasciculus.
To achieve this, the “low-road” or a bottom-up process is used to generate a response to stimuli that are potentially hazardous. The stimulus reaches the thalamus, and information is passed to the lateral nucleus, then the basolateral system, and immediately to the central nucleus where a response is then formed. There is no conscious ...
