Neuroscience Multisensory memoriesPeter SternIn everyday life, we easily form speech memories during casual conversations. Remembering what someone said and how they said it requires the brain to form an integrated multisensory representation of speech. Theta oscillations in the neocortex and the hippocampus are important for episodic memory formation. Biau et al.

Neuroscience You see what you expectPeter SternFeedback from higher-level visual processing centers in the brain influences the early stages of object recognition. PHOTO: EYEEM MOBILE GMBH/ISTOCK PHOTOVisual recognition is thought to start with basic object features in the primary visual cortex, reaching the level of object representation at higher cortical areas after processing. However, there is increasing evidence for top-down influences in these pathways. Altavini et al.

Topological Optics Viewing topology in higher dimensionsIan S. OsborneArtistic depiction of a four-dimensional regular lattice that forms a quasicrystalline pattern with fivefold symmetry when projected in two dimensions. The symmetry and topology of physical systems are closely related to the symmetries governing the topological properties. Quasicrystals are ordered systems but have no translation or rotational symmetries.

Neuroscience Another limitation of working memoryPeter SternMonkeys experience similar challenges in working memory to humans, including erroneously swapping one detail for another. PHOTO: PURIPAT PENPUN/GETTY IMAGESThe well-known limitations of working memory are attributed to the drift of memories over time and the forgetting of items. However, a third type of error, the so-called swap error, is not well understood.
