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)

Chimps show increased latencies to feed, and tendencies to maintain greater distances from possible contaminants and/or outright refusals to consume food in test conditions, hinting at the origins of disgust in humans. […]
Brain is strobing not constant, neuroscience...

It's not just our eyes that play tricks on us, but our ears too. That's the finding of a landmark collaboration that provides new evidence that oscillations, or 'strobes', are a general feature of human perception. While our conscious experience appears to be continuous, the study suggests that perception and attention are intrinsically rhythmic in nature. […]
Paraplegic rats walk and regain feeling after...

Paralyzed rats implanted with engineered tissue containing human stem cells were able to walk independently and regained sensory perception in their hind legs and tail. The implanted rats also show some degree of healing in their spinal cords. The research demonstrates the great potential of stem cells to treat spinal cord injury. […]
Neurobiology: Fixated on food?

Contrast has an impact on the optokinetic reflex, which enables us to clearly perceive the landscape from a moving train. Researchers have now shown that visual features that modulate this ability are encoded in the retina. […]
Consuming nuts strengthens brainwave function
