Remembering David Bucci.
April 15, 2021
In the year of 2021, we are honoring David J. Bucci, our beloved and respected colleague, who died at the age of 50 in 2019. In the Special Section entitled Remembering David Bucci, we reprint 6 of the 29 articles that Dave published in Behavioral Neuroscience beginning with the first one in 1995. O...

Fighting dementia with play
April 9, 2021
A dementia diagnosis turns the world upside down, not only for the person affected but also for their relatives, as brain function gradually declines. Those affected lose their ability to plan, remember things or behave appropriately. At the same time, their motor skills also deteriorate. Ultimately...

Genetic link between face and brain shape
April 5, 2021
Researchers have identified 76 overlapping genetic locations that shape both our face and our brain. What the researchers didn't find is evidence that this genetic overlap also predicts someone's behavioral-cognitive traits or risk of conditions such as Alzheimer's disease. This means that the findi...

Common Alzheimer’s treatment linked to slower cognitive decline
March 25, 2021
Cholinesterase inhibitors are a group of drugs recommended for the treatment of Alzheimer's disease, but their effects on cognition have been debated and few studies have investigated their long-term effects. A new study shows persisting cognitive benefits and reduced mortality for up to five years ...

No evidence that prefrontal HD-tDCS influences cue-induced food craving.
October 1, 2020
This study investigated whether the application of high definition transcranial DC stimulation (HD-tDCS) to the dorsolateral prefrontal cortex reduces cue-induced food craving when combined with food-specific inhibitory control training. Using a within-subjects design, participants (N = 55) received...

Factor structure and concurrent validity of the Cognitive Fusion Questionnaire (CFQ) in a sample of Somali immigrants living in North America.
September 28, 2020
The process of resettlement in a new country and culture is commonly one of intense stress. Somali immigrants and refugees living in North America represent a large ethnocultural group navigating the complexities of forced displacement and resettlement. Despite the immense resilience exhibited by So...

Alzheimer’s gene triggers early breakdowns in blood-brain barrier, predicting cognitive decline
April 29, 2020
New USC research reveals how APOE4, a genetic culprit for Alzheimer's disease, triggers leaks in the brain's plumbing system, allowing toxic substances to seep into the brain areas responsible for memory encoding and other cognitive functions.
The damage is linked to future problems i...

Implant-free optogenetics minimizes brain damage during neuronal stimulation
April 29, 2020
A minimally invasive optogenetic technique that does not require brain implants successfully manipulated the activity of neurons in mice and monkeys, researchers report April 29th in the journal . The researchers first genetically engineered neurons to produce a newly developed, extremely light-s...

Molecular switch plays crucial role in learning from negative experiences
April 29, 2020
Neurobiologists at KU Leuven have discovered how the signalling molecule Neuromedin U plays a crucial role in our learning process. The protein allows the brain to recall negative memories and, as such, learn from the past. The findings of their study on roundworms have been published in the jour...

How the heart affects our perception
April 28, 2020
The first mechanism establishes a relationship between the phase of the heartbeat and conscious experience. In a regular rhythm, the heart contracts in the so-called systolic phase and pumps blood into the body. In a second phase, the diastolic phase, the blood flows back and the heart fills up a...
