      Neuropathic pain-like stimuli can accelerate the ascending pain pathway and eventually induce over-activity of the astrocytes and the suppression of GABA transmission in the anterior cingulate cortex, which may promote sleep disturbance under pain. Activated astrocytes may, at least in part, induce insomnia in patients with neuropathic pain.

    2. Chronic administration of nicotine enhances NMDA-activated currents in the prefrontal cortex and core part of the nucleus accumbens of rats (pages 248–256)

      Nicotine treatment for 14 days induces an increase in NMDA current amplitude that is related to an increase in the number of receptors rather than a possible change in subunit expression.

    3. Phencyclidine rapidly decreases neuronal mRNA of brain-derived neurotrophic factor (pages 257–265)

      Yusuke Katanuma, Tadahiro Numakawa, Naoki Adachi, Noriko Yamamoto, Yoshiko Ooshima, Haruki Odaka, Takafumi Inoue and Hiroshi Kunugi

      The authors show that phencyclidine (PCP), a noncompetitive NMDA receptor blocker, rapidly decreased BDNF mRNA in cultured cortical neurons. PCP mainly reduced transcripts derived from BDNF exon IV through inhibiting CaMKII/CREB signaling.

    4. Cortical dopamine release during a behavioral response inhibition task (pages 266–274)

      This proof-of-principle study sought to determine whether a stop-signal task could induce detectable changes in cortical dopamine. Using [18F]fallypride PET, we found that the stop-signal task elicited significant changes in dopamine in several cortical regions implicated in inhibitory control.

    5. Synchronous alteration pattern between serine-threonine kinase receptor-associated protein and Smad7 in pilocarpine-induced rats of epilepsy (pages 275–282)

      Transforming growth factor β (TGFβ) signaling participates in the epileptogenesis. STRAP and Smad7 synergize in the inhibition of TGFβ signaling. Results indicate that STRAP level was significantly decreased in 24 h, 72 h (acute stage), 1 week (latent stage), 1 month, 2 months (chronic stage), respectively, in the rats model compared with the normal rats by using both western blotting and immunohistochemistry in the hippocampus and temporal lobe cortex of pilocarpine-induced epilepsy rats. Smad7 had similar reduced pattern as STRAP. We concluded that STRAP and Smad7 proteins might be involved in the development of temporal lobe epilepsy.
