Past research findings suggest that women who are addicted to cocaine are more sensitive to cocaine-related stimuli that make them crave the drug and relapse into addiction. However, other studies suggest that steroid hormones can modulate cocaine cravings, which...
To examine the human brain and better understand its functions, neuroscientists have so far used a variety of methods to record the electrical activity of brain cells. Traditionally, these methods were either able to record the activity of a few individual neurons at...
Classical psychological theories suggest that humans and animals consistently employ a single strategy when making decisions. Some models, on the other hand, assume that preferred decision-making strategies can slowly change or evolve over time.
Researchers at Emory University School of Medicine have recently carried out a large-scale analysis of the brains of patients with Alzheimer's disease (AD). Their findings, published in Nature Neuroscience, unveiled a series of disease-related changes in protein...
Neuroscience research suggests that adult male rodents and humans perform better than females on spatial tasks. These are tasks that involve the ability to understand and remember the spatial relationships between different objects in space.
The peripheral nervous system is comprised of all nerves outside of the brain and the spinal cord (i.e., the central nervous system). Peripheral nerves contain a variety of different cell types, including glial cells.
In his most renowned work, "On the Origin of Species," Charles Darwin introduced the idea that species need to continuously fight for their existence, and that only the most fit for a given environment survive. This notion, commonly known as the "survival of the...
The melanin-concentrating hormone (MCH) is a neuropeptide (i.e., a compound that transmits information in the brain) produced by neurons in a region known as the lateral hypothalamic area (LHA). Past studies have found that in rodents, humans and other mammals, this...
The human brain stores and organizes meaningful information in different regions and networks. While past neuroscience studies have examined some of these networks in great depth, the relationship and interactions between them is not yet entirely clear.
Gonadotropin-releasing hormone (GnRH) is the primary hormone regulating sexual reproduction in humans and other mammals. Past neuroscience studies have found that GnRH-producing neurons migrate from a region in the nose known as the nasal placode to the anterior part...
