Immunization with beneficial bacteria makes brain more stress resilient

Rats immunized weekly for three weeks with beneficial bacteria showed increased levels of anti-inflammatory proteins in the brain, more resilience to the physical effects of stress, and less anxiety-like behavior. If replicated in humans, researchers s…

Human drug addiction behaviors tied to specific impairments in 6 brain networks

Systematic review of task-related neuroimaging studies found addicted individuals demonstrate increased activity in these networks during drug-related processing but decreases across all other functions.

Link found between neurotransmitter imbalance, brain connectivity in those with autism

Researchers have identified a link between a neurotransmitter imbalance and brain connectivity between regions of the brain that play a role in social communication and language. The study found two tests that could lead to more precise medical treatme…

How the brain performs flexible computations

Neuroscientists have found that by analyzing neural activity using a mathematical concept known as a dynamical system, they can accurately model how the brain performs tasks that require flexible timing.

A typical communication pattern of people with Alzheimer’s disease

Dementia, in any form, is a heartbreaking disease that can take away one’s thinking and judgement abilities before they pass. To save face, people with dementia often pretend to know answers to questions, even if they really don’t. This often hides the…

Distracted people can be ‘smell blind’

‘Inattentional smell blindness,’ or inattentional anosmia, has been proven to exist. Just as it has previously been found that people can miss visual cues when they are busily engaged in a task, the same is true of smells. However, with smells there is…

What effect does transcranial magnetic stimulation have on the brain?

Researchers have gained new insights on the question of how transcranial magnetic stimulation (TMS) effects functional interconnectivity of neurons. For visualization, they employed fluorescent dyes which provide information on the activity of neurons …

Neurons ripple while brains rest to lock in memories

Researchers develop a computational tool to analyze waves of firing neurons in the hippocampus while animals are at rest and determine which neurons represent the recall or reactivation of patterns linked to specific memories.

Maternal depressive emotion associated with children’s sleep problems

Maternal depressive mood during the prenatal and postnatal periods is related to child sleep disturbances, according to recent pilot data from a longitudinal cohort study in kindergarten children.

Sex robots may do more harm than good

According to their makers, sex robots can bring many health-related benefits to users. But how realistic are these claims? A new study investigates.
