A new study reveals that the human brain can distinguish between thousands of chemicals using a 'fingerprint' pattern, while another discovery sheds light on pheromone-detecting neurons in mice that identify potential mates and social status. These findings may also aid in understanding animal communication and behavior.
Researchers at Imperial College London identified a neural signal called WNT-3 that helps form connections between sensory and motor neurons in the spinal cord. The discovery has important implications for understanding neural regeneration following spinal injury.
A University of Toronto researcher discovered that embryonic motor systems are largely intrinsic to central nervous systems, with rhythmic movements developing even when deprived of sensory input. This suggests that these movements are coded in the intrinsic properties of neurons, sufficient to drive coordinated movement.
A brain protein linked to narcolepsy helps regulate bodily sensations and modulate sensory input from the body. Hypocretin-2 was found to inhibit activity of neurons associated with pain and temperature sensation, suggesting a potential mechanism connecting wakefulness and sensory modulation.
David Julius, PhD, has made a groundbreaking discovery about the capsaicin receptor, VR1, which mediates responses to painful stimuli. His work builds on the pioneering research of Edward R. Perl, who first identified nociceptors as responsible for pain perception.
Researchers have identified a multigene family of candidate pheromone receptors expressed by sensory neurons in the vomeronasal organ, which may recognize different classes of pheromones. The discovery could lead to understanding of innate behaviors and mating behaviors in mice.
