Humans can sometimes perceive the passing of time differently, for instance, feeling as though an hour passed very quickly or that a few minutes went by extremely slowly. This suggests that the human perception of time is subjective and can be affected by many factors...

A new strategy for the viral manipulation of interneurons in mice and other mammals
Study highlights the role of astrocytes in the formation of remote memories
Memories from a distant past, also known as remote memories, can guide the present and future behavior of humans and other living organisms on Earth. In psychology and neuroscience, the term "remote memories" refers to all memories related to events that took place...
Exploring how social touch affects communication between female animals
The sense of touch can significantly affect how animals and humans perceive the world around them, enriching their experiences and allowing them to gather more information about their surroundings and other living organisms. Although touch is a crucial aspect of...
Researchers develop a selective chemogenetic actuator to rapidly control neuronal activity and behavior
Chemogenetics is a fairly new area of neuroscience that explores the use of synthetically derived receptors and selective ligands to temporarily activate or deactivate specific brain areas. These receptors are also known as DREADDs (Designer Receptors Exclusively...
Study identifies neuronal populations that drive defensive behavior in zebrafish
In vertebrates, animals that have a backbone or spinal column, many survival behaviors and physiological states are regulated by the hypothalamus. The hypothalamus is a region in the vertebrate forebrain located below the thalamus, which is known to coordinate the...
A new framework for understanding dynamic representations in networked neural systems
Groups of neurons in the human brain produce patterns of activity that represent information about the stimuli that one is perceiving and then convey these patterns to different brain regions via nerve cell junctions known as synapses. So far, most neuroscience...
Exploring the neural underpinnings of mind wandering
Mind wandering occurs when a person's attention shifts from things that are happening in her present environment to internal thought processes. For instance, while cooking or attending a lesson, one might start thinking about something that happened the day before or...
The role of the hippocampus in how humans mentally travel in time and space
Human and animal brains can represent events in time and space in fascinating ways, for instance, by accessing a chronology of events that happened in the past via stimuli perceived by the senses. In the human brain, spatial and temporal dimensions of events are...
The synchrony between neurons in different brain hemispheres could aid behavioral adaptation
In order to survive and thrive, humans and other living organisms must continuously acquire new strategies to adapt their behaviour to changing environments. Past studies suggest that the synchronization between different brain cells could create flexible brain states...
