Artificial intelligence (AI) draws inspiration from current knowledge of the human brain, artificially replicating some of its learning processes and functions. The extent to which artificial agents successfully emulate the brain's activity, however, is not yet fully...
Anxiety disorders are widespread mental health conditions that affect approximately one in five people. They are characterized by varying degrees of nervousness, apprehension and fear, typically associated with catastrophic thoughts about imagined or potential threats.
Studies exploring the neural processes involved in cell regeneration are of crucial importance, as they could pave the way towards the development of more effective treatments for many pathologies associated with the mutations or deterioration of cells. Microglia, the...
Throughout the course of their life, most humans are likely to experience some form of lower back pain. This pain is sometimes associated with injuries, chronic back issues, medical conditions, the menstrual cycle or pregnancy, and other underlying physiological...
Astrocytes, a sub-population of glial cells with a distinctive star-like shape, are known to play a vital role in numerous neuronal functions, including synaptic support, the regulation of energy metabolism, and the control of blood flow in the brain. While many...
Human beings can sometimes experience dissociative states, moments in which they feel disconnected from their body and the world around them. While these states have been linked to many psychiatric conditions, they can also be elicited by the intake of some legal and...
Feelings of pain and discomfort are crucial to the survival and evolution of animals, as they help to detect injuries or existential threats and pinpoint their location in the body. Pain signals are produced by nociceptors, sensory neurons that respond to damage to...
While many studies have investigated the underpinnings of the mammalian motor system (i.e., the collection of neural networks that allow mammals to move in specific ways), some questions remain unanswered. One of these questions relates to the ways in which recurring...
Some neuroscience studies suggest that distinct human emotional states are associated with greater activity in different regions of the brain. For instance, while some parts of the brain have been associated with all emotional responses, the hypothalamus has often...
Humans perceive tactile information, including pressure, pain, itch, temperature, vibration and movements, thanks to an intricate network of neurons situated in the brain and spinal cord. This network, referred to as the somatosensory system, is now known to be...
