美國波士頓學院和賓州大學的科學家發(fā)現(xiàn)了一種人大腦運轉及識別周圍環(huán)境的新方式,。相關研究發(fā)表在近期的《自然—神經(jīng)科學》雜志上,。
研究人員要求被試者分別看兩組照片：一組是四種場景（廚房、浴室,、道路交叉口和游樂場）,，另一種是上述場景中的個別物體（冰箱、浴缸,、汽車和滑坡）,；之后對被試者大腦進行功能性磁共振成像掃描。
研究人員發(fā)現(xiàn),，被試者能夠利用由個別物體產(chǎn)生的大腦模式來辨認由場景產(chǎn)生的大腦模式,，并且能夠及時說出場景的類型。
該研究領導者肖恩·麥克沃伊（Sean MacEvoy）表示,，該研究揭示了一個大腦利用物體信息來辨別位置的新系統(tǒng),，有助于研發(fā)治療大腦創(chuàng)傷的方法。（生物谷 Bioon.com）

Many persistent pain states (pain lasting for hours, days, or longer) are poorly treated because of the limitations of existing therapies. Analgesics such as nonsteroidal anti-inflammatory drugs and opioids often provide incomplete pain relief and prolonged use results in the development of severe side effects. Identification of the key mediators of various types of pain could improve such therapies. Here, we tested the hypothesis that hitherto unrecognized cytokines and chemokines might act as mediators in inflammatory pain. We used ultraviolet B (UVB) irradiation to induce persistent, abnormal sensitivity to pain in humans and rats. The expression of more than 90 different inflammatory mediators was measured in treated skin at the peak of UVB-induced hypersensitivity with custom-made
