The gut microbiome is the aggregate genome of the microbiota living in the gastrointestinal tract, implicated in numerous host systemic functions, behaviors, and diseases. Past studies have shown probiotics, ingestible … Continue Reading Study finds the microbiota, genetics, and memory are linked.
Bacteria are abundant microscopic organisms found everywhere. Classed as a prokaryotic lifeform due to their unicellular status, they have many roles in nature such as being a source of numerous … Continue Reading Bacteria shown to have working memory similar to neurons.
The part of our sleep cycle involving Rapid Eye Movement (REM), otherwise known as paradoxical sleep, is a crucial phase of sleep identified in mammals and birds involving the random … Continue Reading Researchers identify neurons responsible for rapid eye movements/REM during sleep.
An ever-growing epidemic, obesity is a chronic medical condition where excess body fat has accumulated to the point it may cause a multitude of health disorders. Several studies have also … Continue Reading Visceral fat delivers a signal to the brain that impairs cognition.
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.
Like a myriad of stars interacting with the expanse of space, the brain contains billions of interlaced and communicating neurons supported by the brain’s immune cells, known as glia. The … Continue Reading Researchers show astrocytes are crucial for establishing long-term memory in mice.
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.
DNA is the primary information storage medium in all living organisms and can be harnessed to act as synthetic cellular memory devices, one such DNA-based system harnessed for many different … Continue Reading The world’s smallest tape recorder is built from microbes.
During neurodevelopment, the brain fabricates an incredible number of neurons which then migrate to specific parts of the brain. The development of new neurons is active all the way through … Continue Reading Study identifies how adult brain circuits regulate new neuron production.
The human brain is the source of a person’s thoughts, emotions, perceptions, actions, and memories. One challenge for neuroscience is to achieve an integrated understanding of brain-wide interactions, particularly the … Continue Reading Study identifies new function for the hippocampus.
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.
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.
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.
Alzheimer’s disease is characterized by the degeneration of neurons in the hippocampus and cortex, and the appearance of neuritic plaques and neurofibrillary tangles. Although the precise cause of Alzheimer’s disease remains … Continue Reading Researchers elevate brain protein to allay symptoms of Alzheimer’s in animal model.
Exercise is well-known for its cognitive benefits because it causes neurogenesis, the creation of new neurons, in the hippocampus, which is a key brain region for learning, memory and mood … Continue Reading Research refutes famous study, shows neurons created through exercise don’t erase old memories.
It is known that one of the earliest sites of Alzheimer’s disease pathology is the hippocampus, a brain structure critical for the learning and memory processes that falter early in Alzheimer’s … Continue Reading Study shows how Alzheimer’s risk gene disrupts memory replay.
