Journal ArticleDOI
Increasing adult hippocampal neurogenesis is sufficient to improve pattern separation.
Amar Sahay,Kimberly N. Scobie,Alexis S. Hill,C. O'Carroll,Mazen A. Kheirbek,Nesha S. Burghardt,André A. Fenton,Alex Dranovsky,René Hen +8 more
TL;DR: It is shown that inducible genetic expansion of the population of adult-born neurons through enhancing their survival improves performance in a specific cognitive task in which two similar contexts need to be distinguished, which is indicative of enhanced pattern separation.
Journal ArticleDOI
Modulation of mediotemporal and ventrostriatal function in humans by Delta9-tetrahydrocannabinol: a neural basis for the effects of Cannabis sativa on learning and psychosis.
Sagnik Bhattacharyya,Paolo Fusar-Poli,Stefan Borgwardt,Rocío Martín-Santos,Chiara Nosarti,C. O'Carroll,Paul Allen,Marc L. Seal,Paul C. Fletcher,José Alexandre de Souza Crippa,Vincent Giampietro,Andrea Mechelli,Zerrin Atakan,Philip McGuire +13 more
TL;DR: The modulation of mediotemporal and ventrostriatal function by Delta9-THC may underlie the effects of C. sativa on verbal learning and psychotic symptoms, respectively.
Journal ArticleDOI
Induction of psychosis by Δ9-tetrahydrocannabinol reflects modulation of prefrontal and striatal function during attentional salience processing.
Sagnik Bhattacharyya,José Alexandre de Souza Crippa,Paul Allen,Rocio Martin-Santos,Stefan Borgwardt,Paolo Fusar-Poli,Katya Rubia,Joseph Kambeitz,C. O'Carroll,Marc L. Seal,Vincent Giampietro,Michael Brammer,Antonio Waldo Zuardi,Zerrin Atakan,Philip McGuire +14 more
TL;DR: In this article, the authors investigated whether its psychotic effects are mediated through an influence on attentional salience processing, and found that chronic use of marijuana may increase the risk of schizophrenia.
Journal ArticleDOI
Neural Basis of Δ-9-Tetrahydrocannabinol and Cannabidiol: Effects During Response Inhibition
Stefan Borgwardt,Stefan Borgwardt,Paul Allen,Sagnik Bhattacharyya,Paolo Fusar-Poli,José Alexandre de Souza Crippa,Marc L. Seal,Valter Fraccaro,Zerrin Atakan,Rocio Martin-Santos,C. O'Carroll,Katya Rubia,Philip McGuire +12 more
TL;DR: It is suggested that THC attenuates the engagement of brain regions that mediate response inhibition and CBD modulated function in regions not usually implicated in response inhibition.
Journal ArticleDOI
Effect of image analysis software on neurofunctional activation during processing of emotional human faces
Paolo Fusar-Poli,Paolo Fusar-Poli,Sagnik Bhattacharyya,Paul Allen,José Alexandre de Souza Crippa,José Alexandre de Souza Crippa,Stefan Borgwardt,Stefan Borgwardt,Rocio Martin-Santos,Marc L. Seal,C. O'Carroll,Zerrin Atakan,Antonio Waldo Zuardi,Philip McGuire +13 more
TL;DR: A double analysis of an fMRI dataset using emotional faces revealed comparable whole-group brain responses, and it is unclear to what extent the observed neurofunctional response of the brain cortex during emotional processing depends on the fMRI package used in the analysis.
