Rewriting a Receptor’s Role

Researchers upend a long-held view about the basic functioning of a key receptor molecule involved in signaling between neurons. The study describes how a compound linked to Alzheimer's disease impacts NMDA receptors and weakens synaptic connections between brain cells.

Scientists Turn Off the Ability to Feel Cold

Researchers have isolated chills at a cellular level, identifying the sensory network of neurons in the skin that relays the sensation of cold. By better understanding the specific ways in which we feel sensations, scientists hope to one day develop better pain treatments without knocking out all ability to feel for suffering patients.

Neuroprosthesis Gives Rats the Ability to ‘Touch’ Infrared Light

Researchers have given rats the ability to "touch" infrared light by fitting them with an infrared detector wired to microscopic electrodes implanted in the part of the mammalian brain that processes tactile information. The study demonstrated that a novel sensory input could be processed by a cortical region specialized in another sense without "hijacking" the function of this brain area.

Induction of Mild Inflammation Leads to Cognitive Deficits Related to Schizophrenia

Researchers have identified an exceptional mouse model of schizophrenia. The study identified a mutant mouse lacking the Schnurri-2 protein (Shn-2 KO) that exhibits behavioral deficits and other brain features consistent with schizophrenia.

Reflex Control Could Improve Walking After Incomplete Spinal Injuries

A training regimen to adjust the body's motor reflexes may help improve mobility for some people with incomplete spinal cord injuries. During training, the participants were instructed to suppress a knee jerk-like reflex elicited by a small shock to the leg. Those able to calm hyperactive reflexes saw improvements in their walking.
