The brain is a sophisticated biological system known to produce different experiences and perceptions via complex dynamics. Different brain regions and neural populations commonly work in tandem, communicating with each other to ultimately produce specific behaviors...

Study shows that eye movements decrease while effortfully listening to speech
After a certain age, approximately 40% of people experience some degree of hearing loss. While age-related hearing loss is most prevalent in adults over the age of 65, it can start occurring far earlier than that, when people are in their 40s or 50s.
Exploring the integration of audiovisual information in the primate amygdala and adjacent regions
Humans and other primates can jointly make sense of different types of sensory information, including sounds, smells, shapes and so on. By integrating sensory stimuli in the brain, they can better understand the world around them, detecting potential threats, food and...
Study shows how iron dysregulation might contribute to neurodegenerative diseases
Past neuroscience research consistently found a link between deviations from the "normal" iron metabolism, also known as iron dysregulation, and different neurodegenerative diseases, including Parkinson's disease (PD) and Multiple Sclerosis (MS). Specifically, brain...
Study uncovers distinct time cell populations in the bat hippocampus
The hippocampus is a major region in the brain of vertebrates known to play a key role both in navigation and the encoding of memories and learning. While many neuroscience studies have investigated this brain region's function and its organization, there is still...
Study unveils neural pathway promoting regeneration after traumatic injuries
Studies exploring the neural processes involved in cell regeneration are of crucial importance, as they could pave the way towards the development of more effective treatments for many pathologies associated with the mutations or deterioration of cells. Microglia, the...
Study on rodents shows that the activity of single motor neurons is stable over time
While many studies have investigated the underpinnings of the mammalian motor system (i.e., the collection of neural networks that allow mammals to move in specific ways), some questions remain unanswered. One of these questions relates to the ways in which recurring...
A study on zebrafish explores how the neural circuitry behind odor processing develops over time
Neuroscientists have been trying to understand how animals and humans process sensory information for several decades now. While their work has led to many important discoveries, many questions remain unanswered.
Researchers map mouse olfactory glomeruli using state-of-the-art techniques
Detecting odors and differentiating between them is an essential ability that helps animals to survive and interact more effectively with their surrounding environment. In mammals, odors are known to be initially processed by olfactory sensory neurons, a class of...
Study constructs a molecular and cellular taxonomy of the mouse nucleus accumbens
The nucleus accumbens (NAc) is an area of the brain known to play a key role in regulating a variety of reward-related behaviors, including appetitive and aversive responses, feeding, social interactions and some types of learning. Studies on both humans and animals...
