Recalling memories from an observer-like perspective activates different parts of the brain

Adopting a third-person, observer point of view when recalling your past activates different parts of your brain than recalling a memory seen through your own eyes, according to a new paper.

Granule cells operate as gatekeepers

The hippocampus is a region within the brain that contains many neurons that help us to navigate in space. This leads to the nickname of this area: the GPS of the brain.

Study: Amyloid-beta alters cholesterol biosynthesis in early stages of Alzheimer’s

Korea Brain Research Institute (headed by Suh Pann-ghill) announced on July 24 the discovery that an increase in amyloid-beta in the brain alters cholesterol biosynthesis, which was found by Dr. Cheon Mookyung of KBRI through RNA-seq analysis data (omics) using AI.

'Little brain' contains almost 80% of the cerebral cortex’s surface area

When we say someone has a quick mind, it may be in part thanks to our expanded cerebellum that distinguishes human brains from those of macaque monkeys, for example.

Unfamiliar social interactions can produce negative emotions in people with autism

Some individuals love meeting new people, while others abhor the idea. For individuals with conditions such as autism, unfamiliar social interactions can produce negative emotions such as fear and anxiety.

Harvard neurobiologists provide new insights into the mystery of scent

The premiere of the movie Scent of Mystery in 1960 marked a singular event in the annals of cinema: the first, and last, motion picture debut "in glorious Smell-O-Vision."

Genetic dysfunction of brain astrocytes promotes head pain in familial migraine

Neuroscientists of the University of Zurich shed a new light on the mechanisms responsible for familial migraine: They show that a genetic dysfunction in specific brain cells of the cingulate cortex area strongly influences head pain occurrence.

EEG study in split-brain patients shines light on sleep slow waves

The particular kind of waves that the brain produces during sleep, which repeatedly sweep the surface of the cerebral cortex, travel through the anatomical "highways" that connect distant areas of the cortical mantle, a new study in The Journal of Neuroscience shows.

Inhibitory interneurons excite the developing brain, study finds

Brain function depends on inhibitory cells that balance or 'brake' excitation. These neurons allow the brain to process information and also prevent runaway seizures.

Single-cell-resolution technologies help map brain regions in humans and primates

Using the single-cell-resolution transcriptomics technologies, researchers have performed a large-scale analysis of gene expression in 33 different brain regions of chimpanzees, bonobos, macaques, and humans, and successfully generated a map of the various brain regions with their particular cell structures.

Study identifies brain structure that controls our behavior

For our social life and our profession we must be able to deal with our environment and other people. Executive functions, meaning the basic intellectual abilities that control human thought and action, help us to do this.

New head-mounted microscope allows access to inner workings of the brain

Scientists working at caesar have developed a small head-mounted microscope that allows access to the inner workings of the brain.

Foxg1 gene works like a molecular knob to modulate electrical activity of the neurons

It works like a very fine "molecular knob" able to modulate the electrical activity of the neurons of our cerebral cortex, crucial to the functioning of our brain.

New tool may shed more light on neurodegenerative diseases

About 350 years ago, Robert Hooke provided an initial description of a cell in Micrographia, and since then, microscopy has played a major role in figuring out life’s rules.

Study shows some genetic variants have stronger effects on RNA expression even before birth

The prefrontal cortex of the human brain experiences a wider spectrum of developmental activity right from early prenatal development until childhood.

New microscopy technique reveals movements of cell muscles in unprecedented detail

For the first time, researchers from the University of Warwick have observed the movements of cell muscles in the form of minute filaments of proteins at unparalleled detail.

Memory cells that help to interpret new situations identified

Imagine you are meeting a friend for dinner at a new restaurant. You may try dishes you haven't had before, and your surroundings will be completely new to you. However, your brain knows that you have had similar experiences -- perusing a menu, ordering appetizers, and splurging on dessert are all things that you have probably done when dining out.

Study shows entire brain responds to gut through neuronal connections

The strange feeling in the gut is considered as an innate intuition that emerges from deep within the belly and helps guide the actions of people, if allowed.

Study unveils genetic variants that play key role in psychiatric, neurological conditions

The cerebral cortex is important for memory, thinking, attention, and information processing. It is an outer, folded, and comparatively thin “gray matter” layer of the brain.
