Which part of the brain gen­er­ates doubt?

BBC Earth (Asia) - - Q & A -

Re­searchers re­cently dis­cov­ered that pa­tients with dam­age to the ven­tro­me­dial pre­frontal cor­tex (lo­cated be­hind the eyes), had a ‘doubt-deficit’, in that they were un­usu­ally gullible in re­sponse to mis­lead­ing ad­verts: for ex­am­ple, an ad­vert for a too-good-to-be-true painkiller. But it’s im­por­tant to note that it’s very dif­fi­cult to link com­plex psy­cho­log­i­cal states – such as the ex­pe­ri­ence of doubt – to spe­cific parts of the brain. Many other neu­ral re­gions are likely to be in­volved in the sub­jec­tive ex­pe­ri­ence of doubt, in­clud­ing more emo­tional ar­eas, buried deeper in the brain. CJ
