The contributions in this book integrate knowledge on the structure, function, pathology and clinical .

The contributions in this book integrate knowledge on the structure, function, pathology and clinical manifestations of diseases of the basal ganglia. The basal ganglia are considered by many to be the crossroads of neurology and psychiatry, and it becomes obvious through this book that understanding thereof will require extensive interdisciplinary collaboration.

Anthony J. Franks, Et. . Although the basal ganglia have been studied for many years, their functions have been only recently understood.

Songbirds have emerged as a model system to study how a complex .

Songbirds have emerged as a model system to study how a complex behavioral sequence can be learned through an RL-like strategy. Dopamine (DA) is a key transmitter in the basal ganglia, yet DA transmission does not conform to several aspects of the classic synaptic doctrine.

Most of these models implement multiple distinct basal-ganglia pathways and assume them to fulfill different functions. As there is now a multitude of different models, it has become complex to keep track of their various, sometimes just marginally different assumptions on pathway functions.

Basal ganglia dysfunction causes a set of symptoms that are quite different from damage to descending motor pathways .

Basal ganglia dysfunction causes a set of symptoms that are quite different from damage to descending motor pathways, and thus the basal ganglia were at one time considered to form an extrapyramidal motor system that was distinct from the pyramidal tract pathways. It is now known that the basal ganglia do not originate a separate motor pathway. The basal ganglia comprise a distributed set of brain structures in the telencephalon, diencephalon, and mesencephalon (Figure . and Table 1). The forebrain structures include the caudate nucleus, the putamen, the nucleus accumbens (or ventral striatum) and the globus pallidus.

Basal ganglia dysfunction. Written By: Louise C. Parr-Brownlie. Alternative Titles: basal ganglion, basal nucleus. The basal ganglia refine action signals from the cortex, thereby ensuring that an appropriate motor plan is communicated to the muscles. Unlike the pyramidal pathway, the basal ganglia process information indirectly in a set of loops, whereby they receive input from the cortex and return it to the cortex via the thalamus.

Part I is basically concerned with developmental and evolutionary approaches. Part II highlights relay functions of visual, motor, and somatosensory relay nuclei and relay functions of the intralaminar nuclei. Part III deals primarily with the pharmacology of thalamic neurons.

The contributions in this book integrate knowledge on the structure, function, pathology and clinical manifestations of diseases of the basal ganglia. It comprises an edited version of selected presentations at a conference held on the subject which drew together basic scientists, pharmacologists, pathologists, neurologists, psychologists and psychiatrists from all over the world. The basal ganglia are considered by many to be the crossroads of neurology and psychiatry, and it becomes obvious through this book that understanding thereof will require extensive interdisciplinary collaboration. Research and interest in this part of the brain have been stimulated over recent years by discoveries about the role of subcortical regions in cognitive functions, and the developments of effective treatment for Parkinson's disease. This book thus draws together recent advances and provides an agenda for future research.
