Who is Dr. Iona Yoshida and what publications or affiliations list her work on memory or brain function?

1. Who the sources do identify as “Yoshida” researchers working on memory and brain function

Multiple sources in the dataset document Yoshida laboratories and investigators with a clear publication record in hippocampal physiology, intrinsic persistent firing, temporal association memory and medial temporal lobe (MTL) computation—most prominently Motoharu Yoshida (publications on persistent firing, CA1/CA3 and entorhinal cortex mechanisms) and a Yoshida research group describing neural computation underlying MTL cognitive functions ^{[1] [2] [3]}.

2. What publications list Yoshida work on memory or hippocampal mechanisms

A lab publication list and personal publication pages attribute a string of memory‑related papers and models to “Yoshida M.” including studies on cholinergic receptor activation and persistent firing in entorhinal cortex, intrinsic persistent firing in CA1 pyramidal cells, and models of theta oscillations and memory maintenance in the hippocampus (Behav Brain Res.; Hippocampus; Seibutsu Butsuri) ^[1]. These entries explicitly tie a Yoshida author to mechanisms that have been proposed as substrates for active memory maintenance ^[1].

3. Institutional affiliations and lab listings that surface Yoshida work

Institutional pages and lab profiles in the sources record Yoshida labs and associated impact pages: a Yoshida Lab listing at the Burke Neurological Institute/Weill Cornell aggregate pages appears among associated labs and publication collections (Burke impact/publications listings and profile pages name Yutaka Yoshida and list associated Yoshida labs and publications) ^{[5] [6] [7]}. Separately, the DZNE research‑group page describes a Yoshida group focused on neural computation of MTL cognitive functions and using combined electrophysiology and computational simulation approaches ^[3].

4. Ambiguity around the specific name “Dr. Iona Yoshida” in the supplied reporting

The dataset contains one bibliographic fragment that includes an author listed as “Iona, X.” in a ResearchGate PDF of a multi‑author genetics/brain paper, but that fragment does not show a full name “Iona Yoshida,” an institutional affiliation, or any memory‑focused publications tied to that full name; consequently the reporting does not support asserting that “Dr. Iona Yoshida” is the same person as the various Yoshidas with visible memory publications ^[4]. A non‑scholarly site (brainly.com) speculatively attributes white‑matter research to a “Dr. Yoshida” without authoritative sourcing, which further indicates the potential for name confusion in secondary references ^[8].

5. Conclusion and limits of the reporting

Based on the supplied sources, the more defensible conclusion is that several researchers named Yoshida (Motoharu, Yutaka and others) are well documented as publishing on hippocampal physiology, memory mechanisms and MTL computation ^{[1] [2] [3]}, but there is no clear, citable record in these materials that identifies a distinct “Dr. Iona Yoshida” as an author of memory or brain‑function publications; one citation fragment lists an “Iona” among many coauthors but provides insufficient metadata to confirm identity or link to the Yoshida labs documented elsewhere ^[4]. If the question intends a specific person, additional primary‑source checks (institutional faculty pages, ORCID, PubMed author searches) beyond the supplied reporting will be required to confirm whether “Iona Yoshida” is a distinct researcher and to enumerate her publications and affiliations.
