Brains Of MS Patients Lack Neurosteroids, The Discovery May Open New Route To Treatment PDF Print E-mail
Monday, 26 September 2011 01:16
New research finds that the brains of patients with multiple sclerosis (MS) lack a group of chemicals called neurosteroids which help brain cells repair themselves and do other important things.
How the Brain Makes Memories: Rhythmically PDF Print E-mail
Wednesday, 05 October 2011 07:01

20111005rfns03The brain learns through changes in the strength of its synapses -- the connections between neurons -- in response to stimuli. Now, in a discovery that challenges conventional wisdom on the brain mechanisms of learning, UCLA neuro-physicists have found there is an optimal brain "rhythm," or frequency, for changing synaptic strength.
