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)

Gut communicates with the entire brain through...

You know that feeling in your gut? We think of it as an innate intuition that sparks deep in the belly and helps guide our actions, if we let it. It's also a metaphor for what scientists call the 'gut-brain axis,' a biological reality in which the gut and its microbial inhabitants send signals to the brain, and vice versa.
The facial expressions of mice
on April 2, 2020 at 6:44 pm
Researchers have described different emotional facial expressions for mice. Similar to humans, the face of a mouse looks completely different when it tastes something sweet or bitter, or when it becomes anxious. With this new possibility to render the emotions of mice measurable, neurobiologists can now investigate the basic mechanisms of how emotions are generated and processed in the brain.
How dopamine drives brain activity
on April 1, 2020 at 5:08 pm
Using a specialized magnetic resonance imaging (MRI) sensor that can track dopamine levels, neuroscientists have discovered how dopamine released deep within the brain influences distant brain regions.
Visual feedback enhances activation of muscle...

Visual feedback is just as important as a sense of body position when it comes to the involuntary reflexes that activate muscle movement, says a new study.
What are you looking at? 'Virtual' communication...
on March 30, 2020 at 1:34 pm
When discussions occur face-to-face, people know where their conversational partner is looking and vice versa. With ''virtual'' communication due to COVID-19 and the expansive use of mobile and video devices, now more than ever, it's important to understand how these technologies impact communication. Where do people focus their attention? The eyes, mouth, the whole face? And how do they encode conversation? A first-of-its-kind study set out to determine whether being observed affects people's […]
