Peer review ? Really ?

Found in a "peer-reviewed" journal Advances in Neural Computing – italics mine.

 

Functional magnetic resonance imaging (fMRI) is a new non-hurt measure technique  for  brain  activity which  have  been  used  at  the  study  of  brain  cognition,  locating  nerve activity, medicine, psychology and other domains, and has become one of the  most important way of the study of brain function

 

In general, the general linear model take Gamma function as hemodynamic response function  to  get  design  matrix.  But,  it  is  not  reasonable  in  most  actually  case.  The BOLD signal of the cerebral activation is a collective response of an activated region and it can be explained as a mutual interaction process between the neural response to  a  stimulus  and  the  hemodynamic  change  due  to  the  activation  of  a  neural  cluster.

 

 

It goes in this spirit … but need I bother ?
