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)

Who made the error? The brain distinguishes...

Scientists examined positions to detect motor and target errors and whether error signals from these positions were used for learning, finding that the parietal lobe detected causes of motor errors in arm reaching and provided signals to compensate for errors. They also revealed that Brodmann area 5 detected the self-generated motor error and that Brodmann area 7 detected target error caused by target movements, both providing error signals for adaptation.

Synapse-specific plasticity governs the identity...

Each memory is stored in a specific population of neurons called engram cells. When a memory is linked with another to generate an associative memory, two memory traces overlap. At the same time, individual memories maintain their own identities. Using two overlapping fear memories in mice, researchers show that synapse-specific plasticity guarantees both storage and identity of individual memories. They also show that memory traces no longer exist in the brain after complete retrograde amnesia. […]
Why the left hemisphere of the brain understands...

Nerve cells in the brain region planum temporale have more synapses in the left hemisphere than in the right hemisphere -- which is vital for rapid processing of auditory speech, according to new research. There has already been ample evidence of left hemisphere language dominance; however, the underlying processes on the neuroanatomical level had not yet been fully understood. […]

Researchers have revealed that infants aged 4- to 5-months already hold a primary cerebral representation of audiovisual integration of material information in their right hemisphere, and the number of types of material which can be processed by infants' brain increases with the experience of the materials. This finding may lead to understand the trajectory of acquiring general knowledge about objects around us. […]

A computer built to mimic the brain's neural networks produces similar results to that of the best brain-simulation supercomputer software currently used for neural-signaling research. Tested for accuracy, speed and energy efficiency, this custom-built computer named SpiNNaker, has the potential to overcome the speed and power consumption problems of conventional supercomputers, with the aim of advancing our knowledge of neural processing in the brain, including learning and disorders such as […]
