Genetic fate mapping reveals that the caudal ganglionic eminence produces a large and diverse population of superficial cortical interneurons

G Miyoshi, J Hjerling-Leffler, T Karayannis… - Journal of …, 2010 - Soc Neuroscience
By combining an inducible genetic fate mapping strategy with electrophysiological analysis,
we have systematically characterized the populations of cortical GABAergic interneurons …

…, G Miyoshi, J Hjerling-Leffler, T Karayannis… - Cerebral …, 2009 - academic.oup.com
Ventral telencephalic progenitors expressing the homeodomain transcription factor Nkx6-2
have been shown to give rise to a multitude of cortical interneuron subtypes usually …

Neuronal activity is required for the development of specific cortical interneuron subtypes

NV De Marco García, T Karayannis, G Fishell - Nature, 2011 - nature.com
Electrical activity has been shown to regulate development in a variety of species and in
various structures 1 , including the retina 2 , 3 , 4 , spinal cord 5 , 6 and cortex 5 . Within the …

Prox1 regulates the subtype-specific development of caudal ganglionic eminence-derived GABAergic cortical interneurons

G Miyoshi, A Young, T Petros, T Karayannis… - Journal of …, 2015 - Soc Neuroscience
Neurogliaform (RELN+) and bipolar (VIP+) GABAergic interneurons of the mammalian cerebral
cortex provide critical inhibition locally within the superficial layers. While these subtypes …

Sensory inputs control the integration of neurogliaform interneurons into cortical circuits

…, R Priya, SN Tuncdemir, G Fishell, T Karayannis - Nature …, 2015 - nature.com
Neuronal microcircuits in the superficial layers of the mammalian cortex provide the
substrate for associative cortical computation. Inhibitory interneurons constitute an essential …

The mesoSPIM initiative: open-source light-sheet microscopes for imaging cleared tissue

…, R Pizzala, N Renier, HU Zeilhofer, T Karayannis… - Nature …, 2019 - nature.com

the community is still lacking instruments capable of producing volumetric images of …

[HTML][HTML] An automatic multi-tissue human fetal brain segmentation benchmark using the fetal tissue annotation dataset

…, M Beresova, TD Nguyen, G Natalucci, T Karayannis… - Scientific data, 2021 - nature.com
It is critical to quantitatively analyse the developing human fetal brain in order to fully
understand neurodevelopment in both normal fetuses and those with congenital disorders. To …

Expression of COUP-TFII nuclear receptor in restricted GABAergic neuronal populations in the adult rat hippocampus

P Fuentealba, T Klausberger, T Karayannis… - Journal of …, 2010 - Soc Neuroscience
The COUP-TFII nuclear receptor, also known as NR2F2, is expressed in the developing
ventral telencephalon and modulates the tangential migration of a set of subpallial neuronal …

Slow GABA transient and receptor desensitization shape synaptic responses evoked by hippocampal neurogliaform cells

T Karayannis, D Elfant, I Huerta-Ocampo… - Journal of …, 2010 - Soc Neuroscience
The kinetics of GABAergic synaptic currents can vary by an order of magnitude depending
on the cell type. The neurogliaform cell (NGFC) has recently been identified as a key …

[PDF][PDF] Activity regulates cell death within cortical interneurons through a calcineurin-dependent mechanism

R Priya, MF Paredes, T Karayannis, N Yusuf, X Liu… - Cell reports, 2018 - cell.com
We demonstrate that cortical interneurons derived from ventral eminences, including the
caudal ganglionic eminence, undergo programmed cell death. Moreover, with the exception of …
