Patrones de Inteligencia
La actividad coordinada de las células cerebrales, como la de los pájaros que vuelan en formación, nos ayuda a comportarnos de forma inteligente en situaciones nuevas, de acuerdo con un estudio dirigido por investigadores de Cedars-Sinai.
Patterns of Intelligence
The coordinated activity of brain cells, like birds flying in formation, helps us behave intelligently in new situations, according to a study led by Cedars-Sinai investigators.
Alcohol-related blackouts during youth are markers of future neurocognitive risk
Alcohol-related blackouts (ARBs) are fairly common among younger, social drinkers – even considered a rite of passage by some. Yet new research has found that blacking out predicts unique, underlying brain changes involved with learning, memory, and the processing of visual information.
Making Long-Term Memories Requires Nerve-Cell Damage
Just as you can’t make an omelet without breaking eggs, scientists at Albert Einstein College of Medicine have found that you can’t make long-term memories without DNA damage and brain inflammation. Their surprising findings were published online today in the journal Nature.
An unexpected link between 2 schizophrenia risk proteins
The discovery of a physical interaction between two proteins in brain cells that can be traced in mice to control of movement, anxiety and memory could one day open the door to development of new schizophrenia treatment strategies, researchers say.
Protein p53 regulates learning, memory, sociability in mice
Researchers at the Beckman Institute for Advanced Science and Technology have established the protein p53 as critical for regulating sociability, repetitive behavior, and hippocampus-related learning and memory in mice, illuminating the relationship between the protein-coding gene TP53 and neurodevelopmental and psychiatric disorders.
Penn Medicine Researchers Identify the Link Between Memory and Appetite in the Human Brain to Explain Obesity
Disrupted connections between memory and appetite regulating brain circuits are directly proportional to BMI, notably in patients who suffer from disordered or overeating that can lead to obesity, such as binge eating disorder, according to new research from the Perelman School of Medicine at the University of Pennsylvania.
Discovery of neurons that recognize others
Researchers from the Center for Cognition and Sociality (CCS) within the Institute for Basic Science (IBS) recently announced the discovery of neurons that allow us to recognize others. The research team discovered that the neurons that deal with the information associated with different individuals are located in the CA1 region of the hippocampus.
Neuroscientists identify how the brain links related memories
UCLA scientists have discovered how the brain links memories and a way to restore this function in aging mice–as well as an FDA-approved drug that achieves the same thing. The Nature findings suggest a new method for combatting middle-aged memory loss.
UNLV Research Bolsters Link Between Diabetes and Alzheimer’s Disease
In a study published in the September issue of the journal Communications Biology, UNLV neuroscientists show that chronic hyperglycemia impairs working memory performance and alters fundamental aspects of working memory networks.
Do Genetics Control Who Our Friends Are? It Seems So with Mice.
Have you ever met someone you instantly liked, or at other times, someone who you knew immediately that you did not want to be friends with, although you did not know why? Now, a new study from the University of Maryland School of Medicine (UMSOM) suggests that there may be a biological basis behind this instantaneous compatibility reaction.
New Neuronal Code Found in Bats Navigating Extra-Large Spaces, Weizmann Institute Scientists Report
To date, place cells have been studied in mammals in small spaces. How do we navigate large ones? Prof. Nachum Ulanovsky and team studied bats navigating a 200-m-long tunnel – and discovered a novel neuronal code for spatial perception. The work showed that place cells behave completely differently when navigating very large spaces.
Same Difference: Two Halves of The Hippocampus Have Different Gene Activity
DALLAS – May 28, 2021 – A study of gene activity in the brain’s hippocampus, led by UT Southwestern researchers, has identified marked differences between the region’s anterior and posterior portions. The findings, published today in Neuron, could shed light on a variety of brain disorders that involve the hippocampus and may eventually help lead to new, targeted treatments.
Inhibitory Interneurons in Hippocampus Excite the Developing Brain
A new study from the George Washington University, reports that in some critical structures of the developing brain, the inhibitory neurons cause excitation rather than suppression of brain activity. The findings, published in Science Advances, could have implications for the treatment of neonatal seizures.
Study Explores Effects of AMP-activated Protein on Gamma Wave Patterns in Brain

Neuroimaging links brain region to poor spatial navigation in children affected by prenatal alcohol exposure
Fetal alcohol spectrum disorders (FASD) describe the range of effects associated with prenatal alcohol exposure (PAE). The most severe forms of FASD are fetal alcohol syndrome (FAS) and partial fetal alcohol syndrome (PFAS), which have adverse effects on learning and memory and result in observable physical abnormalities, including a distinct pattern of facial dysmorphic features, small head circumference, and growth restriction. Identifying the specific brain regions affected is important to fully understand the impact of PAE. Poor spatial skills are common in children with FASD, and tests of navigation in rodents – and more recently, humans – have linked PAE to impairment in ‘place learning’ (the learning of physical positions or locations of objects). Place learning in rodents and humans depends on the hippocampus, a small seahorse-shaped structure in each side of the brain. The hippocampus is particularly sensitive to PAE and is smaller in people (and rodents) exposed to alcohol in
UNH Researchers Find Synchronization of Memory Cells Critical For Learning and Forming Memories
Researchers at the University of New Hampshire found that the neurons involved in Pavlovian learning shift their behavior and become more synchronized when a memory is being formed – a finding that helps better understand memory mechanisms and provides clues for the development of future therapies for memory-related diseases like dementia, autism and post-traumatic stress disorder (PTSD).
Epilepsy Study Shows Link Between Brain Activity and Memory
A new study reveals how memory and abnormal brain activity are linked in patients with epilepsy who often report problems with memory. The data show that abnormal electrical pulses from specific brain cells in these patients are associated with a temporary kind of memory disruption called transient cognitive impairment.
Animal Study Shows How Stress and Mother’s Abuse Affects Infant Brain
A new study in rats shows the extent of brain damage in newborn rodents from even short-term abuse by their mother.
