“The amygdaloid complex is involved in anxiety Lapatinib or fear responses to stressful stimuli. In this study the effect of neuropeptide-EI on anxiety-like behavior and its influence on adrenocortical function was tested in male Wistar rats that were injected bilaterally in the basolateral amygdala with neuropeptide-EI (1 mu g/1

mu l) or artificial cerebrospinal fluid and placed on the plus maze. The plasma corticosterone levels were analyzed in controls and plus-maze exposed animals. Neuropeptide-EI in the basolateral

amygdala significantly decreased the time spent in open arms but had no effect on locomotor activity, showing an anxiogenic effect. However, neuropeptide administration did not change serum corticosterone levels compared with vehicle controls. Our results suggest that the anxiogenic effect of neuropeptide-EI could be independent of the hypothalamic-pituitary-adrenocortical system response.

“Functional imaging studies show that motor imagery activates multiple structures in the human forebrain. We now show that phantom movements in an amputee and imagined movements in intact individuals elicit responses from neurons in several human thalamic nuclei. These include the somatic sensory nucleus receiving input from the periphery (ventral caudal), and the motor nuclei receiving input from the cerebellum [ventral intermediate (Vim)] and the basal ganglia [ventral oral posterior (Vop)]. Seven neurons the in the amputee showed phantom movement-related activity (three Vim, two Vop, and two ventral caudal). In addition, seven neurons in a group

of three controls showed motor imagery-related activity (four Vim and three Vop). These studies were performed during single neuron recording sessions in patients undergoing therapeutic treatment of phantom pain, tremor, and chronic pain conditions by thalamic stimulation. The activity of neurons in these sensory and motor nuclei, respectively, may encode the expected sensory consequences and the dynamics of planned movements.

“This study compared the visuospatial asymmetries in children with dyslexia and healthy children by using the manual line bisection task, and investigated the processing of spatial context with a ‘local’ cueing paradigm consisting of geometric symbols placed on the extremities of the lines.
