Disgust is one of the six basic human emotions, along with happiness, sadness, fear, anger, and surprise. Disgust typically arises when a person perceives a sensory stimulus or situation as revolting, off-putting, or unpleasant in other ways.

A minimal cognitive architecture reproduces control of human decision-making processes
Neuroscientists and psychologists have been trying to pinpoint the processes behind human decision-making for decades. While their efforts led to numerous interesting insights, the intricacies of complex decision-making remain poorly understood.
Evidence of a travel direction signal that is independent from head direction in humans
We generally assume that when humans are walking or otherwise moving in space, their head faces towards the direction they are traveling in. Nonetheless, travel direction and head direction are distinct factors associated with the processing of different types of...
Study links organization of neurotypical brains to genes involved in autism and schizophrenia
The organization of the human brain develops over time, following the coordinated expression of thousands of genes. Linking the development of healthy brain organization to genes involved in mental health conditions such as autism and schizophrenia could help to...
Study shows that astrocytes integrate information about past events in their soma
Neurons are known to communicate and integrate information they receive from their dendrites, branch-like structures extending from their body. In contrast, the activity in astrocytes, a class of star-shaped glial cells found in the central nervous system (CNS), has...
Study finds that the transport of mRNAs into axons along with lysosomal vesicles prevents axon degeneration
RNA granules, sites for the storage, transport, and regulation of RNA molecules within cells, are transported along axons and then translated locally, far from the cell body. Recent studies suggest that these granules can "hitch a ride" from lysosome-related vesicles,...

Exploring the origins of excitatory and inhibitory neuronal tuning in the postsubiculum
Brain cells can be broadly divided into two categories: inhibitory and excitatory neurons. Excitatory neurons are cells that support the generation of electrical impulses in postsynaptic neurons, thus prompting the activation of cells in specific brain regions....
Study suggests that stevia is the most brain-compatible sugar substitute
Given the known risks of consuming high amounts of sugar, today many people are looking for alternative sweeteners that produce a similar taste without prompting significant weight gain and causing other health issues. While research suggests that the brain can tell...
How myeloid cell replacement could help treat autoimmune encephalomyelitis
Autoimmune conditions such as multiple sclerosis (MS) are disorders of the immune system associated in this case with demyelination of the central nervous system (CNS). The term demyelination describes damage to the layer covering nerve fibers in the brain and spinal...
