The glia-derived molecule kynurenic acid (KYNA) is an antagonist of alpha7 nicotinic acetylcholine receptors and the glycine(B) binding site on NMDA receptors. KYNA levels are elevated in the brain and cerebrospinal fluid of persons with ...

14 Mar 2009 Maternal care in the rat influences hippocampal development, synaptic plasticity and cognition. Previous studies, however, have examined animals under minimally stressful conditions. Here we tested the hypothesis that maternal care influences ...

10 Mar 2009 In this study we examined changes in a persistent sodium current (I(NaP)) after behavioral aversive classical conditioning in the snail Helix pomatia. We trained animals by pairing food with a mild electric shock that triggered the whole-body ...

10 Mar 2009 Separate studies have implicated the lateral habenula (LHb) or amygdala-related regions in processing aversive stimuli, but their relationships to each other and to appetitive motivational systems are poorly understood. We show that neurons in the ...

7 Mar 2009 The current study was conducted to examine the involvement of muscarinic acetylcholine receptors of the amygdala in morphine-induced state-dependent memory retrieval. Male Wistar rats implanted bilaterally with cannulas in the amygdala were ...

Sex differences in learning processes of classical and operant conditioning.
7 Mar 2009 Males and females learn and remember differently at different times in their lives. These differences occur in most species, from invertebrates to humans. We review here sex differences as they occur in laboratory rodent species. We focus on ...

7 Mar 2009 In 10 patients with central post-stroke pain (CPSP), the influence of ischemia-induced heterotopic noxious conditioning stimulation (HNCS) on the intensity of spontaneous ongoing- and brush-evoked pain was examined. In addition, the modulating ...

7 Mar 2009 This analogue experiment used fear conditioning and extinction procedures to establish and reduce fearful responding and then test for fear renewal following a context change. Healthy undergraduates (N=61) underwent a differential fear conditioning ...

Methotrexate decreases hippocampal cell proliferation and induces memory deficits in rats.
7 Mar 2009 Methotrexate (MTX) is a cytostatic agent used in adjuvant chemotherapy for treatment of breast cancer and is associated with cognitive impairment in a subgroup of patients. The aim of this paper is to test whether MTX can rapidly affect various ...

4 Mar 2009 The present study examined affective processes of social anxiety (SA) through emotional modulation of the startle reflex. Eighty-four high and low trait socially anxious undergraduates viewed socially-relevant and socially-irrelevant pleasant, ...
