sense : (a) faculty of perceiving by means of sense organs (b) specialized function or mechanism (as sight, hearing, smell, taste, or touch) by which an animal receives and responds to external or internal stimuli (c) sensory mechanisms constituting a unit distinct from other functions (as movement or thought) — Webster
Sense A sense is a physiological capacity of organisms that provides data for perception. The senses and their operation, classification, and theory are overlapping topics studied by a variety of fields, most notably neuroscience, cognitive psychology (or cognitive science), and philosophy of perception. The nervous system has a specific sensory nervous system, and a sense organ, dedicated to each sense.
Humans have a multitude of senses. Sight (vision), hearing (audition), taste (gustation), smell (olfaction), and touch (somatosensation) are the five traditionally recognized senses. The ability to detect other stimuli beyond those governed by these most broadly recognized senses also exists, and these sensory modalities include temperature (thermoception), kinesthetic sense (proprioception), pain (nociception), balance (equilibrioception), vibration (mechanoreception), and various internal stimuli (e.g. the different chemoreceptors for detecting salt and carbon dioxide concentrations in the blood, or sense of hunger and sense of thirst). However, what constitutes a sense is a matter of some debate, leading to difficulties in defining what exactly a distinct sense is, and where the borders between responses to related stimuli lie. — Wikipedia (Category)

Skeletal shapes key to rapid recognition of...

In the blink of an eye, the human visual system can process an object, determining whether it's a cup or a sock within milliseconds, and with seemingly little effort. It's well-established that an object's shape is a critical visual cue to help the eyes and brain perform this trick. A new study, however, finds that while the outer shape of an object is important for rapid recognition, the object's inner 'skeleton' may play an even more important role.

Neuroscientists have created interactive maps that can predict where different categories of words activate the brain. Their latest map is focused on what happens in the brain when you read stories.
Optic nerve stimulation to aid the blind

Scientists are investigating new ways to provide visual signals to the blind by directly stimulating the optic nerve. Their preliminary study uses a new type of neural electrode and provides distinct signals.
Type of brain cell involved in stuttering...

Researchers believe that stuttering -- a potentially lifelong and debilitating speech disorder -- stems from problems with the circuits in the brain that control speech, but precisely how and where these problems occur is unknown. Using a mouse model of stuttering, scientists report that a loss of cells in the brain called astrocytes are associated with stuttering. The mice had been engineered with a human gene mutation previously linked to stuttering. The study offers insights into the […]
Traumas change perception in the long-term
on August 19, 2019 at 3:00 pm
Adults who have experienced maltreatment as children have a changed perception of social stimuli. Traumatized people found touch stimuli less comforting than people who had not experienced trauma. They also maintained a greater social distance from strangers. In addition, the researchers discovered changes in the activation of certain brain areas.
