A person’s memory is where the brain encodes, stores, and retrieves information, where it can also be used as a record of experience for guiding learned behavior. Different areas of … Continue Reading Specific neurons responsible for location-based memories decoded and identified.
A person perceives the world around them through multiple senses, with concurrent impulses of signals in different sensory modalities, such as a flash and a beep, readily deciphered and merged … Continue Reading Study develops 4D glasses allowing wearers to be touched by a movie.
The neuronal gene Arc is essential for long-lasting information storage in the brain, mediating various forms of synaptic plasticity and is implicated in neurodevelopmental disorders. However, little is known about … Continue Reading Previously unknown method of neurotransmission identified.
To maintain homeostasis in the body, physiological imbalances produce motivational drives, one of which is thirst. This thirst produces a drive to seek and consume water, however, just how neural activity … Continue Reading Quench thirsting neurons in the brain identified.
The brain controls all functions in the body and interprets information from the outside world with intelligence, creativity, emotion, and memory all governed by the central nervous system. The central … Continue Reading Researchers identify the control mechanism of synapse formation.
The age-old feeling of hunger, driven by negative energy balance, elicits the craving and consumption of food, and whilst this survival response is in part mediated by neurons in the … Continue Reading Two new networks of neurons identified in appetite regulation.
Communication between the gut and brain is thought to control a cornucopia of systems within the body. The gut-brain information highway, also known as the gut-brain axis, is regulated by … Continue Reading Neuron-like cells provide nervous system with window into the gut.
Neurons in an area of the brain known as the hypothalamus control how much an animal eats, however, it is not clear what role the brain’s immune cells, known as … Continue Reading Astrocytes shown to regulate how much we eat.
Welcome to The Top Ten Healthinnovations of 2016, the third-year in our successful series, where the most exciting discoveries and breakthroughs are decided by you, the global medical community. This … Continue Reading The Top Ten Healthinnovations of 2016.
Marijuana is a psychoactive sedative drug and is derived from the hemp plant, Cannabis sativa. Its leaves and buds can be smoked, taken in food, brewed in tea or taken … Continue Reading Neuroimaging shows that marijuana users have low blood flow to the brain.
Pain hypersensitivity can spread to unaffected body regions immediately surrounding the initial insult. Sometimes it can even spread to the opposite site of the body or to large body areas … Continue Reading Pain-initiating function of glial cells identified for the first time.
Autism spectrum disorders (ASD) affect around 1% of the world’s population and are characterized by a range of difficulties in social interaction and communication. There are many different genetic mutations … Continue Reading Researchers identify a new form of autism.
Despite the global medical community’s understanding of the significance of the prefrontal cortex in the consolidation of long-term memories, its role in the encoding of long-term memory remains elusive. Now, a … Continue Reading New study identifies region of brain responsible for conditioned fear memory.
The development of neural connectivity is essential for brain function, and disruption of this process is associated with autism spectrum disorder (ASD). Now, a study from researchers led by McMaster … Continue Reading Study identifies autism gene which regulates dendrite development to slow down brain communication.
A significant milestone in the evolution of the mammalian brain is the emergence of the corpus callosum, which is exclusively present in placental mammals. This commissure forms the largest axon … Continue Reading Neuroimaging shows that astrocytes are responsible for joining the 2 halves of the brain together.
It is known that neurons in the central nervous system of higher vertebrates are formed during embryonic development and that neurogenesis does not occur postnatally, except in the hippocampus. Buried … Continue Reading Researchers sucessfully make memories stronger and more precise during aging in mice.
