Volume 11, Issue 4 , Autumn 2012, Pages 127-134

Abstract
  Background: Chronic daily headache (CDH) has gained little attention in functional neuro-imaging. When no structural abnormality is found in CDH, defining functional correlates between activated brain regions during headache bouts may provide unique insights towards understanding the pathophysiology ...  Read More

Volume 11, Issue 4 , Autumn 2012, Pages 140-145

Abstract
  Background: Learning and memory are the most intensively studied subjects in neuroscience. Two sites of mammalian brain which are important in learning and memory are CA1 region of hippocampus and Purkinje cell layer of cerebellum. So, the aim of present investigation was to study of the effect of ovariectomy ...  Read More

Volume 11, Issue 4 , Autumn 2012, Pages 146-150

Abstract
  Background: The existence of a pathophysiological link between headaches and muscle activity pattern is still being debated. The purpose of this study was to investigate the effect of pain on the timing pattern of the masseter muscle in patients with tension-type headache (TTH) and migraine without aura ...  Read More
