The evolutionary triumph of flower power

..."Because they are a source of pleasure ?a positive emotion inducer ?we take care of them. In that sense they're like dogs. They are the pets of the plant world." Psychologist Haviland-Jones had conducted three studies that tested the ability of flowers to induce positive emotion. The objective was to demons...

Depression gene may weaken mood-regulating circuit

...in activity plays a key role in wiring the brain's emotion processing circuitry during early development, the researchers propose that the short variant leads to stunted coupling in the circuit, a poorly regulated amygdala response and impaired emotional reactivity ?resulting in increased vulnerability to pe...

Study charts origins of fear

...us, an area buried in the forebrain that regulates emotion and memory, as the origin of fear memory. "This is critical as it changes how and where scientists thought fear was developed," says Zhuo, the EJLB-CIHR Michael Smith Chair in Neurosciences and Mental Health.

UCLA imaging study of children with autism finds broken mirror neuron system

...en with autism also showed reduced activity in the emotion centers of the brain, consistent with the hypothesis that this mirroring mechanism may play a crucial role for understanding how others feel and for empathizing with them. All of the children rehearsed the tasks prior to the fMRI scans to assure res...

Research links 'ecstasy' to survival of key movement-related cells in brain

...that has been found to regulate movement, balance, emotion and motivation, and it also affects pleasurable feelings in the brain. Researchers know that a loss of dopamine cells in the brain leads to the development of Parkinson's disease and possibly other movement disorders. Preventing dopamine cells from d...

Pleasure and pain: Study shows brain's 'pleasure chemical' is involved in response to pain too

Anticipation plays a powerful role in human memory, brain study finds

...ly new body of work on the role of anticipation in emotion and clinical disorders, says senior author Jack Nitschke, a UW-Madison assistant professor of psychiatry and psychology.

Computer with brain connections changing quality of life of paralyzed

Fundamental theories regarding consciousness, emotion and quality of life in sufferers of paralysis from Amyotrophic Lateral Sclerosis (ALS, also known as 'Lou Gerhig's disease') are being challenged based on new research on brain-computer interaction. ALS is a progressive disease that destroys neurons ...

Ape gestures offer clues to the evolution of human communication

...al gestures were less closely tied to a particular emotion and, thereby, serve a more adaptable function. For example, a single gesture may communicate an entirely different message depending upon the social context in which it is used. "A chimpanzee may stretch out an open hand to another as a signal fo...
