A new study into how olfaction is encoded in the brain could further understanding of the root cause of epileptic seizures.
PPL2 neurons help modulate the strength of memories.
Those with alexithymia, a psychological condition in which people have difficulty in the emotions they are experiencing, may also have an altered physiological response to olfactory stimulation, researchers report.
Researchers have been able to map odor molecules based on how often they occur in nature with the help of mathematical modeling.
Researchers discovered unique connectivity between the hippocampus and olfactory areas in the brain, a finding which explains why specific odors can trigger powerful memories. The study also reports a loss of sense of smell is associated with depression and a poorer quality of life.
A new study probes the difference between picking up odors by breathing and chewing.
