The ability to detect imminent threats and execute behaviors aimed at protecting oneself, such as hiding, running away or defending oneself, is central to the survival of most animal species. A region of the mammalian brain known to play a key role in threat response is the hypothalamus, which also regulates the release of hormones and other vital bodily functions.

Axions, hypothetical subatomic particles that were first proposed by theoretical physicists in the late 1970s, remain among the most promising dark matter candidates. Physics theories suggest that the interactions between these particles and regular matter are extremely weak, which makes them very difficult to detect using conventional experimental set-ups.

The human brain is known to contain a wide range of cell types, which have different roles and functions. The processes via which cells in the brain, particularly its outermost layer (i.e., the cerebral cortex), gradually become specialized and take on specific roles have been the focus of many past neuroscience studies.

While many research groups worldwide have been searching for dark matter over the past decades, detecting it has so far proved very challenging, thus very little is known about its possible composition and physical properties. Two promising dark matter candidates (i.e., hypothetical particles that dark matter could be made of) are axions and dark photons.

Ferroelectrics are a class of materials that exhibit so-called spontaneous electric polarization, which is the separation of electric charges that can be reversed when an external electric field is applied to them. The dipole moments (i.e., pairs of equal and opposite charges) in these materials can sometimes be arranged in complex configurations known as topological textures.
