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...
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...
Exploring the nature of anomalous psychedelic experiences
Psychedelics are among the most intriguing and mysterious psychoactive substances, as they can radically alter people's perceptions, cognitive processes and emotions. Their unique qualities and their effects on the human brain have made these substances an appealing...
Research unveils patterns in brain activity associated with intergroup conflicts
Researchers at Beijing Normal university and Leiden University have recently carried out a study investigating patterns in neural activity that could be observed in humans during intergroup conflicts (i.e., conflicts between different groups of individuals). Their...
Research identifies neurons that control left and right movements in mammals
Researchers at University of Copenhagen and Karolinska Institute have recently carried out a study investigating the neural underpinnings of a specific locomotor ability in animals, which involves sideways movements (i.e., moving left or right). Their paper, published...
Investigating neural mechanisms underlying individual differences in perception
Researchers at the National Brain Research Centre in Haryana, India, have recently carried out a study exploring the neural mechanisms that may underlie differences in how different people perceive multisensory stimuli. Their paper, published in the European Journal...
