This
research examines the potential for nutritional interventions,
including diet, isolated nutrients and botanical extracts to
improve mood and cognitive function. Certain
classes of bioactive nutrients appear to improve mood and
cognition acutely. Others may protect against age-associated cognitive
decline.

This
stream of research examines the acute and chronic effects of
recreatrional drugs (including MDMA/Ecstasy and alcohol). Alcohol
intoxication "uncalibrates" people so error monitoring and feedback is
impaired. Other recreational drugs have long-term negative behavioural
effects. |
This research
examines the cognitive, mood and physiological effects of alcohol
hangover - an area which is
surprisingly under-researched. Hangover is associated with negative
mood and cognitive deficits whoich suggest reduced cognitive resources.
These have profound effects for day-to-day performance.

There
is a correspondence between the subjective experience of
cognitive strain and the utilisation of central resources. At
the same time, during mental effort a number of physiological responses
serve to facilitate provision of energetic respources. Some cognition
enhancing interventions have similar effects.

The
brain is highly metabolically active, utilising a large percentage of
the body's glucose and oxygen. This research examined the effects of
administration of glucose and oxygen on cognitive function. These
effects seem to be most evident under conditions of high mental effort.
