Every cortical area receives input from the thalamus and projects
to the thalamus. The cortex and thalamus, therefore, are
inseparable partners for sensation, action, and cognition.
Exploring Thalamocortical Interactions provides readers with
foundational knowledge needed to understand the cellular and
circuit properties of thalamocortical networks, and then goes on to
consider new ideas and hypotheses, some of which are quite
speculative. Some of the major themes emphasized throughout the
book include: * the need for a proper classification of
thalamocortical and corticothalamic circuits * the role of spike
timing for thalamocortical and corticothalamic communication and
the mechanisms for modulating spike timing * the organization and
function of corticothalamic feedback projections * the role of
higher order thalamic nuclei in cortico-cortical communication and
cortical functioning * attentional modulation of thalamocortical
interactions * a rethinking of efference copies and distinguishing
neural signals as sensory versus motor Exploring Thalamocortical
Interactions combines foundational knowledge from decades of
research with fresh ideas and hypotheses on how the thalamus and
cortex work together for sensation, action, and cognition.
Almost all of the messages that are received by the cerebral cortex
from the environment or from the body's internal receptors come
through the thalamus and much current thought about perceptual
processing is based on sensory pathways that relay in the thalamus.
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. It
presents a broad overview of important recent advances in these
areas.
* Provides a look at brain structures involved in perception and
action
* Includes summaries by leading investigators in the field
* Presents recent advances in our understanding of brain functions
The thalamus is a group of cells placed centrally in the brain that
serve a critical role in controlling how both sensory and motor
signals are passed from one part of the cerebral cortex to another.
Essentially, all information reaching the cerebral cortex and thus
consciousness is relayed through the thalamus. The role of the
thalamus in controlling the flow of information (such as visual,
auditory, and motor) to the cortex has only recently begun to be
understood. This book provides an in-depth look at the function of
the thalamus and its role as relayer of information to the cerebral
cortex. The authors explore how the thalamus controls messages that
are passed to the cortex and they introduce the novel suggestion
that the thalamus serves a critical role in controlling how
messages pass from one part of the cortex to another. Exploring the
Thalamus is a comprehensive, up-to-date reference for researchers.
It discusses problems concerning the function and structure of the
thalamus and concludes each chapter with thought-provoking
questions regarding future research.
Key Features:
* Focuses on thalamocortical interrelationships
* Discusses important problems concerning the function and
structure of the thalamus
* Concludes each chapter with thought-provoking questions requiring
future research
