Flexibility is good except when it isn’t: Study finds how scientists can reach different conclusions analyzing the same brain scans

Neu­roimag­ing: Many Ana­lysts, Dif­fer­ing Results (Dana Foundation):

For decades, both the research and med­ical com­mu­ni­ties have relied on neu­roimag­ing tools like func­tion­al mag­net­ic res­o­nance imag­ing (fMRI) to give them a win­dow into the liv­ing human brain. Such scans have pro­vid­ed unprece­dent­ed insights into the brain’s struc­ture and func­tion – and the field, as a whole, has used this tech­nique to bet­ter under­stand how the brain gives rise to thoughts, emo­tions, and actions. But as neu­roimag­ing tech­nol­o­gy has advanced, so have the dif­fer­ent analy­sis tools and the num­ber of ways one can eval­u­ate the result­ing data. Now, the results of unique research project, the Neu­roimag­ing Analy­sis, Repli­ca­tion, and Pre­dic­tion Study (NARPS), sug­gest that dif­fer­ent analy­ses can lead to strik­ing­ly dif­fer­ent results from the same data set.

Brain-wave pat­tern can iden­ti­fy peo­ple like­ly to respond to anti­de­pres­sant, study finds (Stan­ford Med­i­cine press release):

“A new method of inter­pret­ing brain activ­i­ty could poten­tial­ly be used in clin­ics to help deter­mine the best treat­ment options for depres­sion, accord­ing to a study led by researchers at the Stan­ford School of Medicine.

Stan­ford researchers and their col­lab­o­ra­tors used elec­troen­cephalog­ra­phy, a tool for mon­i­tor­ing elec­tri­cal activ­i­ty in the brain, and an algo­rithm to iden­ti­fy a brain-wave sig­na­ture in [Read more…] about Machine-learn­ing study finds EEG brain sig­na­tures that pre­dict response to anti­de­pres­sant treatments

How do you respond to unfamiliar music?

by

Music seems to be a social glue. Think of how love songs enhance our roman­tic feel­ings, how march­ing bands inten­si­fy our affin­i­ty for the home team, or how huge rock con­certs make us feel one with a crowd of thou­sands. Music has some spe­cial pow­er to increase our sense of con­nec­tion and help us affil­i­ate with others.

But why? What’s hap­pen­ing in our brains that makes an iso­lat­ed set of sounds res­onate in these ways? A new neu­ro­science study aimed to find out. [Read more…] about How do you respond to unfa­mil­iar music?

New research sug­gests that high­er-lev­el brain func­tions have a major role in los­ing weight. In a study among 24 par­tic­i­pants at a weight-loss clin­ic, those who achieved great­est suc­cess in terms of weight loss demon­strat­ed more activ­i­ty in the brain regions of the lat­er­al pre­frontal cor­tex asso­ci­at­ed with self-con­trol.

Music Acti­vates Regions of the Brain Spared by Alzheimer’s Dis­ease (Uni­ver­si­ty of Utah):

“Ever get chills lis­ten­ing to a par­tic­u­lar­ly mov­ing piece of music? You can thank the salience net­work of the brain for that emo­tion­al joint. Sur­pris­ing­ly, this region also remains an island of remem­brance that is spared from the rav­ages of Alzheimer’s dis­ease. Researchers at the Uni­ver­si­ty of Utah Health are look­ing to this region of the brain to devel­op music-based treat­ments to help alle­vi­ate anx­i­ety in patients with demen­tia. Their research [Read more…] about Brain imag­ing show that patients with Alzheimer’s dis­ease can still remem­ber and enjoy their favorite songs
