Consciousness: Don't Give Up on the Brain

Royal Institute of Philosophy Supplement July 7, 2010 Kenneth Aizawa 13 citations

Abstract In the extended mind literature, one sometimes finds the claim that there is no neural correlate of consciousness. Instead, there is a biological or ecological correlate of consciousness. Consciousness, it is claimed, supervenes on an entire organism in action. Alva Noë is one of the leading proponents of such a view. This paper resists Noë's view. First, it challenges the evidence he...

Altered architecture and functional consequences of the mesolimbic dopamine system in cannabis dependence.

Addiction Biology July 2010 Saturnino Spiga, Alessandra Lintas, Michele Migliore et al.

Cannabinoid withdrawal produces a hypofunction of mesencephalic dopamine neurons that impinge upon medium spiny neurons (MSN) of the forebrain. After chronic treatment with two structurally different cannabinoid agonists, Delta(9)-tetrahydrocannabinol and CP55 940 (CP) rats were withdrawn spontaneously and pharmacologically with the CB1 antagonist SR141716A (SR). In these two conditions,...

The brain-artefact interface (BAI): a challenge for archaeology and cultural neuroscience.

Social Cognitive and Affective Neuroscience June 2010 Lambros Malafouris

Cultural neuroscience provides a new approach for understanding the impact of culture on the human brain (and vice versa) opening thus new avenues for cross-disciplinary collaboration with archaeology and anthropology. Finding new meaningful and productive unit of analysis is essential for such collaboration. But what can archaeological preoccupation with material culture and long-term change...

Adolescent cannabis use and psychosis: epidemiology and neurodevelopmental models

British Journal of Pharmacology June 1, 2010 Daniel T Malone, Matthew N Hill, Tiziana Rubino

Cannabis is one of the most widely used illicit drugs among adolescents, and most users first experiment with it in adolescence. Adolescence is a critical phase for brain development, characterized by neuronal maturation and rearrangement processes, such as myelination, synaptic pruning and dendritic plasticity. The endocannabinoid system plays an important role in fundamental brain...

Neural correlates of focused attention and cognitive monitoring in meditation.

Brain Research Bulletin April 29, 2010 Antonietta Manna, Antonino Raffone, Mauro Gianni Perrucci et al.

Meditation refers to a family of complex emotional and attentional regulatory practices, which can be classified into two main styles - focused attention (FA) and open monitoring (OM) - involving different attentional, cognitive monitoring and awareness processes. In a functional magnetic resonance study we originally characterized and contrasted FA and OM meditation forms within the same...

Innovative approaches to treatment - refractory depression: The ketamine story

Indian Journal of Psychiatry April 1, 2010 T. Rao, Chittaranjan Andrade

Byline: T.S. Rao, Chittaranjan. Andrade Antidepressant drugs have traditionally addressed the monoamine triumvirate: serotonin, noradrenaline, and dopamine. There have been predominantly two mechanisms recruited in drug action - inhibition of monoamine reuptake and inhibition of intravesicular monoamine catabolism. Tianeptine, which increases the synaptic reuptake of serotonin, and mirtazapine,...

Stress reduction correlates with structural changes in the amygdala.

Social Cognitive and Affective Neuroscience March 1, 2010 Britta K. Hölzel, James Carmody, Karleyton C Evans et al.

Stress has significant adverse effects on health and is a risk factor for many illnesses. Neurobiological studies have implicated the amygdala as a brain structure crucial in stress responses. Whereas hyperactive amygdala function is often observed during stress conditions, cross-sectional reports of differences in gray matter structure have been less consistent. We conducted a longitudinal MRI...

The exploration of meditation in the neuroscience of attention and consciousness.

Cognitive Processing February 1, 2010 Antonino Raffone, Narayanan Srinivasan

Many recent behavioral and neuroscientific studies have revealed the importance of investigating meditation states and traits to achieve an increased understanding of cognitive and affective neuroplasticity, attention and self-awareness, as well as for their increasingly recognized clinical relevance. The investigation of states and traits related to meditation has especially pronounced...

MDMA ("ecstasy") impairs learning in the Morris Water Maze and reduces hippocampal LTP in young rats.

Neuroscience Letters January 29, 2010 Alejandra Arias-Cavieres, Carlos Rozas, Miguel Reyes-Parada et al.

3,4-Methylenedioxymethamphetamine (MDMA), an important recreational psychostimulant drug, was examined for its ability to alter visuo-spatial learning and synaptic plasticity. Young rats received MDMA (0.2 and 2mg/kg s.c.) twice per day for 6 days while their visuo-spatial learning was tested using the Morris Water Maze. After this, animals were sacrificed and LTP induced in hippocampal slices....

Is our brain hardwired to produce God, or is our brain hardwired to perceive God? A systematic review on the role of the brain in mediating religious experience.

Cognitive Processing November 1, 2009 Alexander A Fingelkurts, Andrew A Fingelkurts

To figure out whether the main empirical question "Is our brain hardwired to believe in and produce God, or is our brain hardwired to perceive and experience God?" is answered, this paper presents systematic critical review of the positions, arguments and controversies of each side of the neuroscientific-theological debate and puts forward an integral view where the human is seen as a...
