Abstract Mild Cognitive Impairment (MCI) is a diagnostic category indicating cognitive impairment which does not meet criteria for dementia such as Alzheimer’s disease. There are public health concerns about disease (AD) prompting intervention strategies to respond predictions the impacts of ageing populations and decline. This relationship between MCI AD rests on three interrelated principles,...
OBJECTIVE Parkia biglobossa stem bark decoction is a popular medicinal plant preparation used as calming agent for tensed patients in traditional medicine. The aim of this study was to evaluate the effects of aqueous stem bark extract of Parkia biglobossa (AEPB) and its active fraction AEPBF3 on anxiety, spontaneous alternation behavior, and locomotor activity. The open field apparatus was used...
Thirteen adult Rhesus monkeys were repeatedly perfused through the ventriculocisternal or ventriculolumbar spaces with Elliott's B solution containing various concentrations of methotrexate (MTX) and trace amounts of [3H]MTX and [carboxy-14C]inulin. The concentrations of MTX ranged from 4.8 to 0.15 mg/ml representing perfusion dosages of 551 mg/sq m to 16 mg/sq m. The average steady-state conce...
The object of the current study is to explore the neural substrate for effects of atomoxetine (ATX) on inhibitory control in school-aged children with attention deficit hyperactivity disorder (ADHD) using functional near-infrared spectroscopy (fNIRS). We monitored the oxy-hemoglobin signal changes of sixteen ADHD children (6-14 years old) performing a go/no-go task before and 1.5 h after ATX or...
Combining neuropharmacological experiments with computational modeling, we have shown that cholinergic modulation may enhance associative memory function in piriform (olfactory) cortex. We have shown that the acetylcholine analogue carbachol selectively suppresses synaptic transmission between cells within piriform cortex, while leaving input connections unaffected. When tested in a computation...
