Severe brain injuries or head traumas in humans can lead to various stages of so-called disorders of consciousness (DoC). These are states in which consciousness is either partly or entirely absent, such as a coma; unresponsive ...
Neuroscientists have been trying to understand how animals and humans process sensory information for several decades now. While their work has led to many important discoveries, many questions remain unanswered.
Detecting odors and differentiating between them is an essential ability that helps animals to survive and interact more effectively with their surrounding environment. In mammals, odors are known to be initially processed ...
Alarm pheromones are substances that send danger signals to different parts of the brain. When these signals are perceived by other pheromones of the same class, they can act as cues that alert humans or animals about a potential ...
(Medical Xpress)—The olfactory system is a particular favorite among the many who study neural coding. One reason for this is that presentation of a single odorant to an otherwise featureless smellscape, at least in theory, ...
Humans and other mammals can sometimes experience itch, an uncomfortable sensation that prompts them to scratch specific parts of their bodies. Past studies on humans and other primates have found that itch can sometimes ...
A team of chemical and biological engineers at Seoul National University in the Republic of Korea has developed a proof-of-concept device that could one day lead to the creation of an artificial nose.
Scientists have further decoded how mammalian brains perceive odors and distinguish one smell from thousands of others.

(Medical Xpress)—As occurred in the painstaking deciphering of Egyptian hieroglyphs, adherence to outmoded ideas is a lasting impediment to our understanding of how odorants are decoded by the olfactory system. The primary ...
An Arizona State University researcher is calling into question recent findings that the human nose is capable of distinguishing at least 1 trillion odors. Rick Gerkin, an assistant research professor with ASU School of Life ...
