The first articles for the new Wiley Open Access journal, Brain and Behavior, are now posted online:

ORIGINAL RESEARCH: Comparison of weight changes following unilateral and staged bilateral STN DBS for advanced PD
by Eric M. Lee, Ashish Kurundkar, Gary R. Cutter, He Huang, Barton L. Guthrie, Ray L. Watts, Harrison C. Walker

  This paper explores whether unilateral and bilateral subthalamic nucleus deep brain stimulation in Parkinson’s disease might lead to sustained weight gain postoperatively. To this end, the authors implement a case-control comparative study to evaluate weight changes in patients with Parkinson’s disease over a two year period.
Keywords: Bilateral; deep brain stimulation; Parkinson’s disease; subthalamic; unilateral; weight
REVIEW: Epidemic of illicit drug use, mechanisms of action/addiction and stroke as a health hazard
by Katherine Esse, Marco Fossati-Bellani, Angela Traylor and Sheryl Martin-Schild
  In this comprehensive review article, the authors discuss evidence linking the use of illicit drugs, such as cocaine, amphetamines, ecstasy, heroin, phencyclidine, lysergic acid diethylamide, and marijuana, and increased risk of major cerebrovascular events.  They review epidemiological data and mechanisms of action, particularly those leading to stroke, available from papers published in English in PubMed during 1950 through February 2011.

Keywords: Acute ischemic stroke; illicit drugs; intracerebral hemorrhage; subarachnoid hemorrhage; substance abuse

ORIGINAL RESEARCH: Neural bases of gaze and emotion processing in children with autism spectrum disorders
by Mari S. Davies, Mirella Dapretto, Marian Sigman, Leigh Sepeta and Susan Y. Bookheimer
  In this functional magnetic resonance imaging paper, the authors investigate the effects of gaze direction on neural processing of emotional faces in typically developing (TD) children and those with autism spectrum disorders (ASD). Only TD children and not ASD children showed reliably greater activity in ventrolateral prefrontal cortex when viewing faces with direct versus averted eye gaze, evidence that suggests children with ASD have altered processing of the emotional significance of direct gaze.

Keywords: Autism; facial expression; functional magnetic resonance imaging; gaze; developmental neuroimaging
