Researchers recently developed a system for observing real-time brain activity in a live mouse. The device could prove useful in studying new treatments for Alzheimer’s and other neurodegenerative diseases.
A new study suggests that blood may hold clues to whether post-menopausal women may have an increased risk for brain damage that can lead to memory problems and an increased risk of stroke.
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.
Researchers discover a new way to influence the serotonin signaling system. The findings could lead to more effective medications with fewer side effects.
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.
Researchers suggest the overexpression of a protein called alpha-synuclein appears to disrupt vital recycling processes in neurons. The study may have major implications for more fully understanding the causes and mechanisms of Parkinson’s disease.
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.
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.
Researchers visualize the molecular changes in a critical cell death protein that force cells to die. Defects in cell death have been linked to the development of diseases such as cancer and neurodegenerative conditions.
Working with patients with electrodes implanted in their brains, researchers show that areas of the brain work simultaneously to recall memories. The approach promises new insights into how we remember details of time and place.
