DESCRIPTION:La série Feindel Brain and Mind Seminar s’inscrit dans la ligne
  de pensée du Dr William Feindel (1918-2014)\, directeur du Neuro de 1972 
 à 1984\, qui consiste à maintenir un lien constant entre pratique clinique
  et recherche. Les présentations porteront sur les dernières avancées et d
 écouvertes en neuropsychologie\, en neurosciences cognitives et en neuro-i
 magerie. \n\nLes scientifiques du Neuro\, ainsi que des collègues et colla
 borateurs venus du milieu ou du monde entier\, se chargeront des conférenc
 es. Cette série se veut un forum virtuel pour les chercheurs et les stagia
 ires en vue de favoriser les échanges interdisciplinaires sur les mécanism
 es des troubles cérébraux et cognitifs\, leur diagnostic et leur traitemen
 t. \n\n\nPour assister en personne\, inscrivez-vous ici\n\nPour regarder v

 t memory systems\, dependent on separate parts of the brain\, can sustain 
 successful navigation. The hippocampus is implicated in spatial memory str
 ategies used when finding one’s way in the environment\, i.e. it is alloce
 ntric and involves remembering the relationship between landmarks. On the 
 other hand\, another strategy dependent on the caudate nucleus can also be
  used\, i.e. the response strategy\, which relies on making a series of st
 imulus-response associations (e.g. right and left turns from given positio
 ns that act as stimuli\, such as turn right at the white building). Adults
  who use spatial memory strategies showed increased fMRI activity in the h
 ippocampus\, increased grey matter in the hippocampus\, and better overall
  cognition compared to adults who use response strategies. Decades of rese
 arch in my laboratory has shown that specific navigation strategies are as
 sociated with several genes\, such as BDNF and ApoE\, as well as hormones\
 , such as cortisol and progesterone. Experiences dependent modulators such
  as age\, habit\, stress and rewards also modulate strategies dependent on
  the hippocampus and caudate nucleus. Moreover\, certain technologies such
  as Global Position Systems (GPS) or video games inhibit the use of the hi
 ppocampus and are associated to poor spatial memory. These results have im
 portant implications on mental health because a larger hippocampus has bee
 n associated with healthy cognition in normal aging and with a reduced ris
 k of numerous neurological and psychiatric disorders such as Alzheimer’s d
 isease\, Schizophrenia\, Post-Traumatic Stress disorder and Depression.\n
