Dysregulation of the hypothalamo-pituitary-adrenal (HPA) axis reduces hippocampal volumes and prefrontal cortex (PFC) activity in depressed patients and disrupts homeostasis within the neurocircuit of depression. Antidepressant drugs increase brain-derived neurotrophin‚ restoring neuronal growth and activity and modulate interactions between the neurocircuit

effects of a deprived or enriched environment on neuroplasticity‚ in particular‚ the development of neurons in the cerebral cortex. The participants used were rats. The rats were separated and exposed to the two environments‚ one enriched with toys and one deprived with no toys for 30-60 days before being euthanized. Rats in the stimulating environment had a thicker cortex and heavier frontal lobe compared to rats in the deprived environment. This study showed the effect of the environment on physiology

The age old question is what is love? The Oxford English Dictionary defines love as “ An intense feeling of deep affection” . Love is a universal topic. When people hear the word “love” many things can come to mind. It is unique because everyone loves differently. Love can be pleasant or torturous.

In the late 1950’s the Playmates released

It is currently unclear‚ however‚ how the ongoing developmental processes impact upon the folding of the cerebral cortex and how changes in gyrification relate to maturation of GM/WM-volume‚ thickness and surface area. In the current study‚ we acquired high-resolution (3 Tesla) magnetic resonance imaging (MRI) data from 79 healthy subjects (34 males and 45 females)

The acute effects of cigarette smoking on memory task performance have been investigated in a number of studies‚ using a variety of measures. However‚ reviews of the effects of nicotine on human cognitive performance have concluded that the findings are very mixed (Heishman et al.‚ 1993; Roth et al.‚ 1992; Sherwood‚ 1994; Wesnes and Parrott‚ 1992). For instance‚ Roth et al.‚ (1992‚ p.253.) noted: ‘Smoking and nicotine effects on memory are contradictory. Improvement‚ no change‚ and impairment have
