Past studies have found that the brains of some animals generate representations of the direction in which they are headed. For instance, the heading direction of insects is represented by the activity of neurons in a region at the center of their brain, known as the...
While pain and fear are very different experiences, past studies showed that they can sometimes be closely related to one another. For instance, when many animals and humans are in dangerous or life-threatening situations, acute fear can suppress their perception of...
Past neuroscience studies suggest that when deciding their next actions, mice and other rodents tend to replay past outcomes of similar situations in their brain, which is reflected in a rapid activation of certain brain regions in a sequence. Recently, some studies...
The hippocampus is a key region of the mammalian brain, which has been found to be involved in the formation of episodic memories. These are long-term memories of events or experiences that can be consciously remembered and mentally re-experienced, such as...
Psychology theories suggest that humans tend to primarily invest significant mental resources on problems that will reward them for their efforts. More specifically, they propose that before they start thinking in great depth about a problem, humans ponder on whether...
Humans are innately able to separate information regarding others in their social circle depending on their needs and what they are looking for. For instance, they might contact a friend who is a lawyer if they need advice with a legal matter or contact an empathetic...
For decades, neuroscientists have been trying to understand the neural mechanisms underpinning different social behaviors, including aggression. Aggressive, violent, or confrontational behaviors are common among humans and many animal species, yet the neural processes...
Autism spectrum disorder (ASD) is a developmental disorder associated with difficulties in interacting with others, repetitive behaviors, restricted interests and other symptoms that can impact academic or professional performance. People diagnosed with ASD can...
Before undergoing surgeries and other invasive medical procedures, patients typically undergo anesthesia. Anesthesia consists in giving patients a class of drugs (i.e., anesthetics) that cause them to lose feeling in specific areas of the body (i.e., local anesthesia)...
In recent years, machine learning techniques have accelerated and innovated research in numerous fields, including neuroscience. By identifying patterns in experimental data, these models could for instance predict the neural processes associated with specific...
