Hippocampal Cells Track Pronouns to Link Them With People

A new study reveals that certain brain cells, known as “concept cells,” in the hippocampus track pronouns to link them with the correct person in a sentence. Researchers found that these cells respond not only to a person’s name or image but also to pronouns like “he” or “she” that refer to them.

Study Links Hippocampus to Control of Skilled Movements

The hippocampus, traditionally linked to memory, also plays a crucial role in skilled actions like typing, handwriting, and playing music. This study challenges the long-held belief that motor skills are exclusively managed by motor regions like the basal ganglia and cerebellum.

How the Brain Encodes Time and Experiences

A new study reveals how specific brain cells in the hippocampus and entorhinal cortex encode time and experiences, helping us form memories and predict future outcomes. These neurons fire in patterns reflecting the order of events, even replaying them after the experience is over. This groundbreaking discovery provides insight into how the brain integrates "what" and "when" information to form lasting memories.

Environment and Hippocampal Size Impact Depression in Youth

Challenging social environments and the size of the left hippocampus in children aged 9-11 contribute to an increased risk of depression. Researchers found that children with larger hippocampal volumes are more sensitive to negative social environments, amplifying depressive symptoms over a two-year period.

Mapping Fear: Brain Circuit That Detects and Remembers Threats Revealed

A new study has mapped a brain circuit responsible for detecting threats and forming fear memories. The hippocampus, known for spatial navigation, also plays a role in recognizing dangers, with the subiculum transferring threat information to the hypothalamus.

Brain Stores Multiple Copies of Single Memory

Memories are not static; they adapt over time to help us respond to new situations. Researchers have discovered that the hippocampus stores multiple copies of a single memory, each within different neuron groups that develop at different stages. These copies vary in their persistence and flexibility, influencing how memories can be modified or recalled. Understanding these dynamics may lead to new ways to address memory-related disorders.

How the Brain Learns to Make Inferences

Researchers have uncovered how the brain processes inferential reasoning by recording neuron activity in individuals as they learned through trial and error. The study revealed that specific brain regions, particularly the hippocampus, create geometric neural representations when people successfully infer new rules from prior knowledge.

Hippocampus Distinguishes Urgent from Future Goals

Researchers discovered how the brain prioritizes immediate and distant goals. Their study found that the hippocampus processes urgent goals faster and differently than future goals. This insight could help understand psychiatric disorders like depression, which affect goal-setting abilities. The findings reveal crucial differences in brain activity and behavior related to goal prioritization.

Brain Ripples Reveal Daydreams’ Origins

Researchers discovered a link between "sharp-wave ripples" in the hippocampus and self-generated thoughts like daydreaming. These ripples, originating in the memory center of the brain, were more frequent during sleep and associated with vivid, imaginative thoughts. Understanding this brain activity could shed light on various mental conditions.

Unlocking Sleep’s Role in Emotional Health

A new study illuminated the mechanisms by which sleep aids in processing emotional memories, crucial for mental health. The research synthesizes over two decades of data to reveal how neurotransmitters like serotonin and noradrenaline, inactive during REM sleep, facilitate the recalibration of emotional experiences.
