Researchers supply major results for understanding the thalamus, the 'relay center' of the brain
The thalamus is the central translator in the brain: Specialized nerve cells (neurons) receive information from the sensory organs, process it, and transmit it deep into the brain. Researchers from the Institute ...

Scientists discover an organizing principle for our sense of smell
The fact that certain smells cause us pleasure or disgust would seem to be a matter of personal taste. But new research at the Weizmann Institute shows that odors can be rated on a scale of pleasantness, and this turns out ...

Highlight: Chloride increases response to pheromones and odors in mouse sensory neurons
The vomeronasal organ (VNO) is an odor detection system that mediates many pheromone-sensitive behaviors. Vomeronasal sensory neurons (VSNs), located in the VNO, are the initial site of interaction with odors and pheromones. ...

Sensory system
A sensory system is a part of the nervous system responsible for processing sensory information. A sensory system consists of sensory receptors, neural pathways, and parts of the brain involved in sensory perception. Commonly recognized sensory systems are those for vision, hearing, somatic sensation (touch), taste and olfaction (smell).
The receptive field is the specific part of the world to which a receptor organ and receptor cells respond. For instance, the part of the world an eye can see, is its receptive field; the light that each rod or cone can see, is its receptive field. Receptive fields have been identified for the visual system, auditory system and somatosensory system, so far.
