Novel imaging method maps brain-wide changes in neuronal connections
Neurons communicate with each other by passing millisecond-long signals across tiny junctions called synapses. Experiences cause the strength of these connections to change—a process called synaptic plasticity, which underlies ...

How perceptions are influenced by expectations: Songbird study draws parallels with human speech processing
Past neuroscience and psychology studies have shown that people's expectations of the world can influence their perceptions, either by directing their attention to expected stimuli or by reducing their sensitivity (i.e., ...
Protein ratio in cerebrospinal fluid outperforms traditional biomarkers in predicting Alzheimer's cognitive decline
A potential new biomarker for predicting future cognitive resilience versus decline among people with early Alzheimer's disease is described in Nature Medicine. This protein signature may improve the ability to predict symptom ...

What drives our cravings for food and drink? Neurons in the amygdala may play a key role
To ensure we get the calories and hydration we need, the brain relies on a complex network of cells, signals, and pathways to guide us when to eat, drink, or stop. Yet, much about how the brain deciphers the body's needs ...

Short-term reactivation of brain between encoding of memories enhances recall, study finds
Past neuroscience and psychology studies have shown that after the human brain encodes specific events or information, it can periodically reactivate them to facilitate their retention, via a process known as memory consolidation. ...
What makes the human brain unique? We compared it with monkeys and apes to find out
Scientists have long tried to understand the human brain by comparing it to other primates. Researchers are still trying to understand what makes our brain different from our closest relatives. Our recent study may have brought ...
