Neuroimage
. 2023 Apr;
274:120121.
PMID: 37080347
Awake rodent fMRI is increasingly common over the use of anesthesia since it permits behavioral paradigms and does not confound normal brain function or neurovascular coupling. It is well established...

J Cereb Blood Flow Metab
. 2021 Nov;
42(5):826-843.
PMID: 34826373
Intracerebral cell therapy (CT) is emerging as a new therapeutic paradigm for stroke. However, the impact of physical therapy (PT) on implanted cells and their ability to promote recovery remains...

Neuroimage
. 2020 Oct;
225:117457.
PMID: 33069862
Functional MRI responses are localized to the synaptic sites of evoked inhibitory neurons, but it is unknown whether, or by what mechanisms, these neurons initiate functional hyperemia. Here, the neuronal...

Poplawsky A, Fukuda M, Kang B, Kim J, Suh M, Kim S
Neuroimage
. 2017 Aug;
197:657-667.
PMID: 28822749
Contrast-enhanced cerebral blood volume-weighted (CBVw) fMRI response peaks are specific to the layer of evoked synaptic activity (Poplawsky et al., 2015), but the spatial resolution limit of CBVw fMRI is...

Poplawsky A, Fukuda M, Kim S
Neuroimage
. 2017 May;
199:718-729.
PMID: 28502845
Laminar organization of neuronal circuits is a recurring feature of how the brain processes information. For instance, different layers compartmentalize different cell types, synaptic activities, and have unique intrinsic and...

Layer-Specific fMRI Responses to Excitatory and Inhibitory Neuronal Activities in the Olfactory Bulb
Poplawsky A, Fukuda M, Murphy M, Kim S
J Neurosci
. 2015 Nov;
35(46):15263-75.
PMID: 26586815
Significance Statement: Functional magnetic resonance imaging (fMRI) is a noninvasive, in vivo technique widely used to map function of the entire brain, including deep structures, in animals and humans. However,...

Neuroimage
. 2014 Feb;
92:312-21.
PMID: 24495813
Compressed sensing (CS) may be useful for accelerating data acquisitions in high-resolution fMRI. However, due to the inherent slow temporal dynamics of the hemodynamic signals and concerns of potential statistical...

Neuroimage
. 2014 Jan;
91:237-51.
PMID: 24418506
The olfactory bulb is a laminarized brain structure involved in odor sensation that has important implications to basic neuroscience research, like mechanisms for neurovascular coupling and early disease diagnosis. To...
