'''Michel le Moal''', born on 28 September 1934 in [[Le Havre]], is a [[Neuropsychiatry|neuropsychiatrist]] and French researcher in [[neuroscience]]. He is considered to be the initiator in France of research aimed at establishing relationships between [[Behavior|behaviour]] and neuroscience and at creating an integrative [[neurobiology]].

== Biography ==
Pupil of the Nation ([[Rocroi]] Court, 1943), he completed his secondary studies in [[Givet]] (in the Ardennes), then at the [[Lycée Henri-IV|Lycée Henri IV]] (in [[Paris]]), and at the Lycée de [[Brest, France|Brest]].

SPCN at the [[Faculty of Sciences]] in Paris (1952), then preparatory class (Brest Maritime Hospital) for the entrance exam to the National School of the Marine Health Service (1953); entry to the School (1954), [[Bordeaux]]. At the same time, he continued his medical studies at the Faculty of Medicine. Interruption (1959-1961) for treatment in Sanatorium, [[Isère]]. During medical training (Doctorate in 1968), decides to focus on what was still [[neuropsychiatry]]; after specialty internship (1968), chooses child neuropsychiatry; this activity will cease in 1978. In addition to medicine, he completed his training: Bachelor of Arts ([[Philosophy]], [[Psychology]]) 1962, Bachelor of Science ([[Chemistry]] - [[Physiology]]) 1962. Doctorate of State in Science, at 40 years of age (Thesis supervisor: Pierre Karli).

From 1964 onwards, he was assistant and then assistant professor at the Faculty of Science in Bordeaux. From 1975 to 1976, he was a post-doctoral fellow at the [[California Institute of Technology]] (Caltech) at J. Olds' Laboratory. Then professor of Neurosciences, from 1976, and until 2005. From 1980 to 2004, he was Director of Studies at the [[École pratique des hautes études|École Pratique des Hautes Études]] (EPHE 3rd section), in Experimental Psychopathology. From 1993 to 2003, he was a Member of the [[Institut Universitaire de France]].

Professor emeritus at the University of Bordeaux, he has headed several [[French National Centre for Scientific Research|CNRS]] and [[Inserm]] units, then designed and directed the Institut François Magendie de Neurosciences (Inserm - CNRS). Michel le Moal is considered to be the initiator in France of research aimed at establishing relationships between behaviour and neuroscience and at creating an integrative neurobiology<ref>Liquid error: wrong number of arguments (given 1, expected 2)</ref>. In order to understand the transition from adaptation to disadaptation, he laid the foundations for experimental psychopathology. In recent years, the neurobiology of addiction has been the focus of attention. He has been a member of the French Academy of sciences since 2005<ref>Liquid error: wrong number of arguments (given 1, expected 2)</ref>. He received the Neuropsychopharmacology Award in 2005<ref>Liquid error: wrong number of arguments (given 1, expected 2)</ref>.

He attempts to explain the relationship to drugs by integrating an individual's history and education into the cellular functioning of the brain<ref>Liquid error: wrong number of arguments (given 1, expected 2).</ref>.

Advances in behavioural neuroscience and psychiatric research, as well as his many interviews with [[Henri Laborit]], were the reasons for Le Moal's stays in the United States since the late 1970s, where progress was rapid. At Caltech, he learned the methods of multiple intracerebral computer recording in animals free of movement, then at the Salk and Scripps, the basics of Neuroendocrinology and Neuropharmacology and in all these laboratories the behavioural approaches and the need for integrative Neuroscience and the difficulties of modelling in experimental Psychopathology.

From 1974 to 1980, his publications focused on:

*    the role of a ventral neural system including the [[Neurotransmitter|neurotransmitters]] [[dopamine]], [[Norepinephrine|noradrenaline]], or [[serotonin]], in motivational processes; stimulation (intracerebral self-stimulation) causes attention arousal, pleasure phenomena, and injury the inability to focus, uncontrolled hyperactivity,
*    the functional roles of [[dopaminergic]] systems in their frontal cortical projections; identification of memory syndromes resulting from their local lesions and their specific intracerebral stimulation and blockages; analysis of the neural bases of individual and species survival behaviours; discovery of the central roles of the CRF and [[vasopressin]] in adaptive behaviours<ref><abbr>(en)</abbr> Stinus L, Gaffori O, Simon H, Le Moal M., « Disappearance of hoarding and disorganization of eating behavior after ventral mesencephalic tegmentum lesions in rats », ''J Comp Physiol Psychol. 92(2): 289-296'',‎ 1978</ref> <ref><abbr>(en)</abbr> Gaffori O, Le Moal M., « Disruption of maternal behavior and appearance of cannibalism after ventral mesencephalic tegmentum lesions », ''Physiol Behav. 23(2): 317-323.'',‎ 1979</ref>.

From 1980 to 1995, his research on the modalities of the transition from normal to pathological was based on methods of behavioural analysis and their measurement<ref><abbr>(en)</abbr> Koob GF, Le Moal M, Gaffori O, Manning M, Sawyer WH, Rivier J, Bloom FE., « Arginine vasopressin and a vasopressin antagonist peptide: opposite effects on extinction of active avoidance in rats », ''Regul Pept. 2(3): 153-163.'',‎ 1981</ref> <ref><abbr>(en)</abbr> Le Moal M, Koob GF, Koda LY, Bloom FE, Manning M, Sawyer WH, Rivier J., « Vasopressor receptor antagonist prevents behavioural effects of vasopressin. », ''Nature. 291(5815): 491-493.'',‎ 1981</ref> <ref><abbr>(en)</abbr> Sutton RE, Koob GF, Le Moal M, Rivier J, Vale W., « Corticotropin releasing factor produces behavioural activation in rats », ''Nature. 297(5864): 331-333.'',‎ 1982</ref> <ref><abbr>(en)</abbr> Koob GF, Dantzer R, Bluthé RM, Lebrun C, Bloom FE, Le Moal M., « Central injections of arginine vasopressin prolong extinction of active avoidance », ''Peptides. 7(2): 213-218.'',‎ 1986</ref> <ref><abbr>(en)</abbr> Le Moal M, Bluthé RM, Dantzer R, Bloom FE, Koob GF., « The role of arginine vasopressin and others neuropeptides in brain-body integration. », ''In: Cognitive Neuro Chemistry.

It studies the consequences of harmful environments, aggressions (stress) and proposes the measurement of specific markers acting centrally (including the stress system and its central receptors, the neurons involved). He will be the first to set up lifetime studies, for example based on prenatal stress; he will demonstrate the behavioural consequences, including attention disorders, self-regulation and progression to [[Drug-addiction|drug addiction]].

From 1995 to 2005, in continuity with previous results, Le Moal focused the work of its teams on a fundamental question of [[Psychopathology]]: why some subjects succumb and others do not, or show resilience; thus the causes of interindividual, genetic, developmental and environmental differences. The underlying neuro-adaptive processes will be studied on the basis of vulnerability to addictions, the effects of chronic stress, and pathological aging. These analyses will use cognitive, emotional, hormonal, molecular and hormonal approaches<ref><abbr>(en)</abbr> Piazza PV, Le Moal ML., « Pathophysiological basis of vulnerability to drug abuse: role of an interaction between stress, glucocorticoids, and dopaminergic neurons », ''Annu Rev Pharmacol Toxicol. 36: 359-378.'',‎ 1996</ref> <ref><abbr>(en)</abbr> Piazza PV, Le Moal M., « The role of stress in drug self-administration », ''Trends Pharmacol Sci. 19(2): 67-74.'',‎ 1996</ref> <ref><abbr>(en)</abbr> Koob GF, Le Moal M., « Reward neurocircuitry plasticity and the "dark side" of drug addiction », ''Nat Neurosci. 8: 1442-1444.'',‎ 2005</ref>.
