Neural and behavioral signatures of the multidimensionality of manipulable obje...
Almeida, Jorge; Fracasso, Alessio; Kristensen, Stephanie; Valério, Daniela; Bergström, Fredrik; Chakravarthi, Ramakrishna; Tal, Zohar; Walbrin, JonathanUnderstanding how we recognize objects requires unravelling the variables that govern the way we think about objects and the neural organization of object representations. A tenable hypothesis is that the organization of object knowledge follows key object-related dimensions. Here, we explored, behaviorally and neurally, the multidimensionality of object processing. We focused on within-domain object informatio...
The cerebellum is causally involved in episodic memory under aging
Almeida, Armando; Martins, Ana R.; Amaral, Lénia; Valério, Daniela; Bukhari, Qasim; Schu, Guilherme; Nogueira, Joana; Spínola, MónicaEpisodic memory decline is a major signature of both normal and pathological aging. Many neural regions have been implicated in the processes subserving both episodic memory and typical aging decline. Here, we demonstrate that the cerebellum is causally involved episodic memory under aging. We show that a 12-day neurostimulation program delivered to the right cerebellum led to improvements in episodic memory pe...

Valério, Daniela; Santana, Isabel; Sousa, Diana Aguiar de; Schu, Guilherme; Leal, Gabriela; Pavão Martins, Isabel; Almeida, JorgeValério, D et al., Knowing how to do it or doing it? A double dissociation between tool-gesture production and tool-gesture knowledge, Cortex, https://doi.org/10.1016/j.cortex.2021.05.008; Deciding how to manipulate an object to fulfill a goal requires accessing different types of object-related information. How these different types of information are integrated and represented in the brain is still an open qu...
Face-Specific Perceptual Distortions Reveal A View- and Orientation-Independent...
Almeida, Jorge; Freixo, Andreia; Tábuas-Pereira, Miguel; Herald, Sarah B.; Valério, Daniela; Schu, Guilherme; Duro, Diana; Cunha, Gil; Bukhari, QasimThe spatial coordinate system in which a stimulus representation is embedded is known as its reference frame. Every visual representation has a reference frame [1], and the visual system uses a variety of reference frames to efficiently code visual information [e.g., 1-5]. The representation of faces in early stages of visual processing depends on retino-centered reference frames, but little is known about the ...
