Słaba wiedza psychiatrów na temat neuronauki

Mayada Akil, Senior Advisor to the NIMH Director,Professor of Psychiatry at Georgetown University School of Medicine, Director of Outpatient Programs in the Department of Psychiatry at the Georgetown University Hospital jest zdania, że psychiatrzy oraz lekarze mają małą wiedzę na temat neuronauki i nie potrafią z niej korzystać.

Roboty upolują i nagrają aktywność neuronów

W badaniach eksperymentalnych na żywych zwierzętach roboty potrafią już znaleźć i zarejestrować aktywność kilkudziesięciu neuronów jednocześnie. Pozwala to określić w jaki sposób neurony są połączone pomiędzy sobą i które z nich przekazują informacje.

The Space in Your Head

Space, and events associated with places and spaces, are represented in the brain by a circuitry made of place cells, head direction cells, grid cells, and border cells. These cell types form a collective dynamic representation of our position as we move through the environment. How this representation is formed has remained a mystery. Is it acquired, or are we born with the ability to represent external space (see the Perspective by ? investigated the early development of spatial activity in the hippocampal formation and the entorhinal cortex of rat pups when they first began to explore their environment.

Langston et al. Development of the Spatial Representation System in the Rat,  SCIENCE, June 18 2010, 328 (5985),   Wills et al.  Palmer and Lynch)

Rudiments of place cells, head direction cells, and grid cells already existed when the pups made their first movements out of the nest. A neural representation of external space at this early time points to strong innate components for perception of space. These findings provide experimental support for Kant's 200-year-old concept of space as an a priori faculty of the mind.

8 Scientists Share $3 Million in Prizes

Scientists competing to build humongous telescopes, elucidate the machinery by which brain cells signal each other and manipulate individual atoms and molecules into submicroscopic structures were among the winners of one of the richest prizes in science.

The neuroscience prize will also be shared three ways, by Thomas Südhof of the Stanford School of Medicine, Richard H. Scheller of Genentech and James E. Rothman of Yale for work on the molecular basis of nervous transmission. In the 1980s, Dr. Südhof and Dr. Scheller decoded the genes that control the functioning of tiny bubbles of fluid called vesicles, which send neurotransmitters across the synapses between cells. In particular, they found that a protein that senses calcium acts as a switch for transmission. Dr. Rothman investigated how the vesicles involved in a wide range of physiological activities are generated and fuse together.
