New neurons are generated in the hippocampus each day and their survival is greatly enhanced through effortful learning (Shors, 2014). The numbers of cells produced can be increased by physical exercise (van Praag, Kempermann, & Gage, 1999). These findings inspired us to develop a clinical intervention for humans known as Mental and Physical Training, or MAP Training. Each session consists of...

Purely psychological treatments for emotional distress produce lasting, measureable, and reproducible changes in cognitive and emotional consciousness and brain function. How these changes come about illustrates the interplay between brain and consciousness. Studies of the effects of psychotherapy highlight the holistic nature of consciousness. Pre and post treatment functional Magnetic...

Recent attention has been focused on the long-term impact of cannabis exposure, for which experimental animal studies have validated causal relationships between neurobiological and behavioral alterations during the individual's lifetime. Here, we show that adolescent exposure to Δ(9)-tetrahydrocannabinol (THC), the main psychoactive component of cannabis, results in behavioral and...

Cannabinoid exposure during adolescence has adverse effects on neuroplasticity, emotional behavior, cognition, and reward sensitivity in adult rats. We investigated whether escalating doses of the cannabinoid receptor 1 (CB1 R) agonist, HU-210, in adolescence would affect adult hippocampal neurogenesis and behavioral processes putatively modulated by hippocampal neurogenesis, in adult male and...

Chronic pain is often managed using a multidisciplinary, biopsychosocial approach. Interventions targeting the biological, psychological, and social aspects of both the patient and the pain have been demonstrated to provide objective and subjective improvement in chronic pain symptoms. The mechanism by which pain attenuation occurs after these interventions remains to be elucidated. While there...

Cannabis is the most widely used illicit drug, and disruption of learning and memory are commonly reported consequences of cannabis use. We have previously demonstrated a spatial learning impairment by ∆(9)-tetrahydrocannabinol (THC) in adolescent Sprague-Dawley rats (Steel et al., 2011). The molecular mechanisms underlying behavioural impairment by cannabis remain poorly understood, although...

The quantum dynamics of consciousness, cognition and creativity are entangled in seemingly mysterious relationships with the classical Newtonian world view.Penrose, for example, believes that a completely new theory is required to integrate the classical and quantum perspectives on the royal road to reality.Mathematicians and physicists typically address such issues with questions about how...

Recreational drug use among pregnant women is a source of concern due to potential harmful effects of drug exposure on prenatal and infant development. The simultaneous abuse of ecstasy [3,4-methylenedioxymethamphetamine (MDMA)] and alcohol is prevalent among young adults, including young expectant mothers. Here, we used a rat model to study the potential risks associated with exposure to...

Studies in neuroscience demonstrate that a focus on mindfulness meditation and contemplative spiritual practice has the capacity to increase our non-anxious awareness and significantly lower our stress. Not only is this finding of immediate importance for pastoral counselors and psychotherapists, it will even necessitate a paradigm shift in the way that pastoral and spiritual practitioners...

Subjectivity, intentionality, self-awareness and will are major components of consciousness in human beings. Changes in consciousness and its content following different brain processes and malfunction have long been studied. Cognitive sciences assume that brain activities have an infrastructure, but there is also evidence that consciousness itself may change this infrastructure. The two-way...
