Trosolwyg
Rydym yn astudio datblygiad a phlastigrwydd y cortecs gweledol cynradd (V1) a sail ffisiolegol a moleciwlaidd anhwylderau datblygiadol cyffredin golwg fel llygad diog yn ogystal ag anhwylderau niwroddatblygiadol fel Fragile X a syndrom Timotheus. Mae gennym ddiddordeb hefyd mewn prosesu gweledol mewn meysydd gweledol uwch a'i berthynas ag ymatebion ymddygiadol. Mae prosesu gofodol a chof gofodol yn y cortecs ôl-blygiadol (RSC) yn ganolbwynt pwysig arall o ymchwil yn ein labordy. Gan ddefnyddio delweddu calsiwm dau ffoton, rydym yn delweddu gweithgaredd niwronau unigol yn y rhanbarthau o ddiddordeb i'r ymennydd ac yn eu holrhain dros amser.

Ymchwil
Rydym yn astudio mecanweithiau datblygiad arferol a phlastigrwydd y cortecs gweledol cynradd (V1) a sail ffisiolegol a moleciwlaidd anhwylderau datblygiadol cyffredin golwg fel amblyopia (llygad diog). Yn benodol, rydym yn archwilio effeithiau gwahanol gyfundrefnau magu ar ddwy brif nodwedd ymateb niwronau yn y dewis V1, y binocularity a'r cyfeiriadedd dewis. Mae ymchwil dros yr 20 mlynedd diwethaf wedi nodi nifer fawr o foleciwlau a llwybrau sy'n ymwneud â phlastigrwydd datblygiadol yn ogystal ag wrth reoleiddio'r cyfnod critigol y mae'r cortex yn arbennig o agored i gael ei siapio gan brofiad synhwyraidd ac yn wir mae angen profiad priodol i ddatblygu fel arfer. Dangoswyd bod diffygion genynnau sy'n effeithio ar rai o'r proteinau cysylltiedig yn achosi anhwylderau niwroddatblygiadol fel Fragile X. Rydym yn astudio plastigrwydd datblygiadol yn V1 mewn modelau o'r anhwylderau hynny gan ddefnyddio dulliau delweddu'r ymennydd swyddogaethol, sef delweddu optegol signalau cynhenid a microsgopeg sganio laser dau ffoton.
Gan gydnabod bod ymatebion niwronau yn V1 yn aml yn methu â rhoi cyfrif am ymatebion ymddygiadol yr anifeiliaid rydym yn ymchwilio i feysydd gweledol uwch a'u rhagamcanion adborth â V1, ac yn cysylltu'r rheini â'r dewisiadau y mae llygod yn eu gwneud mewn tasgau gwahaniaethu ar sail weledol. Mae gennym ddiddordeb hefyd yng nghyfraniadau mewnbwn o'r cortecs cingulate i haen 1 o V1 i ymddygiad a arweinir yn weledol.
Yn ddiweddar, mae prosesu visuospatial a chof gofodol yn y cortecs ôl-splenial (RSC) wedi dod yn ganolbwynt mawr o ymchwil yn ein labordy. Mae'r RSC wedi dod i'r amlwg fel ardal ymennydd allweddol sy'n cefnogi cof episodig a thopograffig mewn bodau dynol yn ogystal â chof gofodol mewn cnofilod. Gan ddefnyddio delweddu 2-photon in vivo i ddadansoddi patrymau gweithgarwch niwronau o fewn RSC Dysgranular o lygod a hyfforddwyd ar dasg cof ofodol, dangosom ymddangosiad graddol patrwm cyd-destun-benodol o weithgarwch niwronau dros gyfnod o 3 wythnos, a ail-nodwyd ar ôl adalw fwy na 3 wythnos yn ddiweddarach. Roedd sefydlogrwydd yr engram cof hwn yn rhagfynegol o faint o anghofio; Roedd amgramau mwy sefydlog yn gysylltiedig â pherfformiad gwell, gan ddangos cyfranogiad yr RSC mewn storio cof gofodol ar lefel ensembles niwronau.
