[Book Review: Exploring the Thalamus and Its Role in Cortical Function. Second Edition. Article in The Quarterly Review of Biology 82(2) June with 12 Reads. Two leading authorities on thalamocortical connections consider how the neural circuits of the brain relate to our actions and perceptions. In this book, two leading authorities on the thalamus and its relationship to cortex build on their earlier findings to arrive at new ways of thinking about how the brain relates to the world, to cognition, and behavior.

  The thalamus is a brain structure of the vertebrate diencephalon that plays a central role in regulating diverse functions of the cerebral cortex. In traditional view of vertebrate neuroanatomy, the thalamus includes three regions, dorsal thalamus, ventral thalamus, and epithalamus.   Many of the ascending pathways to the thalamus have branches involved in movement control. In addition, the recently defined, rich innervation of ‘higher’ thalamic nuclei (such as the pulvinar) from pyramidal cells in layer five of the neocortex also comes from branches of long descending axons that supply motor structures.

  The thalamus (from the Greek word meaning “chamber”) is centrally located between the cerebral cortex and the midbrain and is known for its role in relaying sensory and motor signals to the cerebral cortex, and in the regulation of sleep, consciousness, and alertness—rather like a hub of information flow from the senses to the cortex.   The epithalamus is the posterior part of the is located posteroinferior to the thalamus and consists of the pineal body, stria medullaris and habenular trigone. Historically, the pineal gland was considered to be the third eye because of its connections to the visual system. But we now know that pineal gland function is to control the sleep-wake cycle (circadian rhythm) by.

Jones () gave the tripartite division of the thalamus. That is, it consists of three parts, viz. the dorsal, ventral, and epithalamus. Among these three divisions, it is only the dorsal thalamus which both sends to receives fibres from the cerebral cortex and striatum.

Rather, the thalamus itself may play a critical role in transmitting information between cortical areas or in coordinating the activity of different cortical areas.

Presentations by Larry Abbott, Carol Colby, David Van Essen, Murray Sherman, and Harvey Swadlow explored the mutually dependent nature of cortical and thalamic activities. The thalamus also regulates sleep and wakefulness. It plays a huge role in connections with the cerebral cortex, which is believed to be involved with consciousness.

The thalamus plays a major role in regulating the level of awareness and activity associated with everyday function and alertness. Clinical Differentiation: Cortical vs. Subcortical Strokes: Cortical: Subcortical: A stroke may affect cortical regions of the cerebral cortex, including the frontal, parietal, temporal and occipital lobes, or structures subcortically, below the cortex, including the internal capsule, thalamus, basal ganglia, brainstem and cerebellum.

The thalamus plays a critical role in perceptual processing, but many questions remain about what thalamic activities contribute. This volume focuses on three major areas: the role of thalamocortical communication in cognition and attention; the role of the thalamus in communication between cortical areas; the hypothesis that much or all of the information relayed by thalamus, even to classical, pure "sensory" areas of cortex, represents a corollary message being sent simultaneously to motor centers.

(Middle panel) On its recruitment by the mPFC, the mediodorsal thalamus (MD) is critical for amplifying and sustaining cortical activity during the delay, which is critical for task performance [based on Bolkan et al.

The thalamus plays a critical role in perceptual processing, but many questions remain about what thalamic acitivities contribute to sensory and motor functions.

In this book, two pioneers in research on the thalamus examine the close two-way relationship between the thalamus and the rest of the brain.

Thalamus is involved in sensory as well as motor functions of the brain. It is the part of the brain where the sensory information from all over the body converge and are then sent to various areas of the cortex.

It also helps the motor cortex for coordinated voluntary movements of the part. Thus, it has an important role in motor cognition. 3) As noted above, the thalamus serves as an integrative center for cortical function.

Some thalamic nuclei (association relay nuclei) receive inputs from one or more regions of cerebral cortex (via corticothalamic axons) and send outputs to other cortical areas, notably association cortex in frontal, parieto-temporo-occipital, or limbic regions.

The authors are 2 leading figures in the study of the intrinsic characteristics and functional role of the thalamus. Their emphasis has long been on the visual system, and the book reflects this bias.

Even so, key points of thalamic function can be generalized from the visual system. The thalamus translates neural impulses from various receptors to the cerebral cortex. While the thalamus is classically known for its roles as a sensory relay in visual, auditory, somatosensory, and gustatory systems, it also has significant roles in motor activity, emotion, memory, arousal, and other sensorimotor association functions.

The mediodorsal nucleus of the thalamus (MD) has been implicated in executive functions (such as planning, cognitive control, working memory, and decision-making) because of its significant interconnectivity with the prefrontal cortex (PFC). Yet, whilst the roles of the PFC have been extensively studied, how the MD contributes to these cognitive functions remains relatively unclear.

The thalamus plays a critical role in perceptual processing, but many questions remain about what thalamic activities contribute to sensory and motor functions.
