Study Sheds Light on how to Reset the Addicted Brain - Could drug addiction treatment of the future be as simple as an on/off switch in the brain? A study in rats has found that stimulating a key part of the brain reduces compulsive cocaine-seeking and suggests the possibility of changing addictive behavior generally.

A new study pinpoints working memory as a source of learning difficulties in people with schizophrenia. Working memory is known to be affected in the milli .

Images: 30 DIV Hippocampal Cultures. IF detection of MAP-2 (green) and GFAP (red) in 30 DIV (A–C) cultured E18 hippocampal cells using a 40X objective. Images (A and B) clearly depict the physical contact between glia processes & dendritic arbors. Under closer examination (CI and CII), it is clear the dendrites have grown both bellow (blue arrows) & above (white arrows) glial processes, forming a highly interconnected three-dimensional network by 30 DIV…

Towards Neuronal Organoids: A Method for Long-Term Culturing of High-Density Hippocampal Neurons

Nerve bundle cross section:  Axons (orange) are wrapped in myelin (purple).

A cross section of a bundle of nerve fibers. Axons (orange) are wrapped in myelin (purple); an extension of the membrane of glial cells. Myelin has high lipid content, and acts to insulate the axons, causing them to transmit nerve impulses much faster.

Zebrafish: Neurons are labeled with multiple colors

Flashy Fluorescent Fish: Neurons in a larval zebrafish are distinguished using the Brainbow method, in which different ratios of a handful of colored fluorescent proteins are expressed randomly to give each neuron a unique hue.
