Several years ago I was visiting the laboratory of a colleague who studies the behavior of birds when I observed something that I considered to be spooky. He had two banks of cages in the lab, containing about a dozen-and-a-half white birds. I was discussing an academic issue with him when I suddenly noticed that almost all of the birds were standing in their individual cages with their heads and bodies pointed in the same direction. It was obvious that the birds were not looking at something that they found interesting, since they were looking slantwise away from the open mesh cage door which gave a clear view of the laboratory.
When I asked my colleague what was going on, he smiled and said, "It's fall, and if these birds were out in the wild they would be preparing to migrate back to the south. A bunch of researchers have been able to show that these birds, and many others, have a magnetic sense, so that they can tell where north and south is. So the reason they are all oriented in the same direction is that they are attuned to that magnetic information and are responding to it by facing south."
About a year or so after that incident I encountered a piece of research which seemed to provide evidence that domestic dogs also perceive the Earth's magnetic fields and even respond to small variations in geomagnetism. The data was subtle, but it demonstrated that under calm magnetic field conditions dogs showed behavior that was influenced by magnetism. Specifically, the researchers looked at when dogs marked their home territory by urinating or defecating. At these times the dogs tended to align their bodies roughly along the north-south magnetic axis. During unstable magnetic field conditions (such as during geomagnetic storms caused by variations in the "solar wind") this directional preference disappeared. While that study seemed to indicate that dogs were responding to magnetism, it left a lot of questions unanswered, such as "What mechanisms allow dogs to detect magnetic fields?" and "How is this ability useful for them?" But I suppose that the question that nagged at me the most as a psychologist was whether the dogs were simply being subtly and unconsciously influenced by these magnetic fields or were they actually perceiving something which they could consciously process and cognitively respond to.
The answer to my question appears in a recent report published by a team of researchers headed by Sabine Martini of the Department of General Zoology at the University of Duisburg-Essen in Essen, Germany. Their reasoning was that if dogs were consciously aware of magnetic fields then this perception could be used to train dogs to make specific discriminations, just like one might train dogs to respond to a particular shape or sound.
The setup sounds a bit strange at first, but it does make sense. The researchers took three large brown glass jars, placed a bar magnet in one, and a brass unmagnetized bar in each of the others. Lids were then placed on the jars to keep out any potential odor cues. The notion was that the magnetic effects would easily pass through the glass and if dogs perceive these in some way then they could use that that information to select the jar containing the magnetized target. As a control condition, three glass jars were used again but this time one of the jars contained a food treat. Once more the jars were sealed and since no odors could escape and the contents of the jar could not be clearly seen it seemed unlikely that the dogs would ever detect the presence of the food contained within.
These experiments seem to support the existence of a magnetic sense in dogs, and further, seem to prove that something about the magnetic field is actually registering in the dogs' conscious perception of the world. Why this ability evolved in dogs, and whether this magnetic sense is used in helpful or adaptive ways to guide a dog's behavior both still remain unanswered questions.
Just like Jaws scared people away from swimming, this scene made me afraid of getting up in the middle of the night to pee. One of the reasons why is that it seemed like something that could possibly happen to me. After all, I was around the same age as Cole.
It turns out that the actress behind the ghoulish glare and bruise makeup is a lovely woman named Janis Dardaris. When I talked to her over the phone, I brought her back to 1999 and described the sense of inescapable fear I felt during her scene, shuddering in a stadium seat of my local theater.
In Buddhist analysis this sense of self occurs in relation to mental consciousness, mano- viāna (Sanskrit: vijāna), one of six forms of cognitive awareness. Each of the first five forms of sensory cognitive awareness arises in response to something impinging upon its respective sense faculty (including the sense organ). As such, it is always disjunctive, that is, it only occurs when there has been a distinct change in its cognitive field. Moreover, it is the internal structure of the faculty itself that determines what is capable of impinging upon it; what is visible depends on the eye faculty. Internal structure and external stimuli in this sense are strictly correlative, and together they co-determine the form (ākāra) of any cognitive object. Mental cognitive awareness is described in exactly the same way: it too only arises with certain causes and conditions.
Unlike sensory forms of cognitive awareness, however, mental cognitive awareness arises with two types of stimuli. The first is a previous moment of sensory cognitive awareness. For example, in one moment a visual stimulus impinges on the visual sense faculty and a form of visual cognitive awareness arises. That is not yet knowing, just a simple seeing. But in the very next moment, that first moment of visual cognitive awareness itself becomes the object of awareness by impinging upon the mental faculty so that a moment of mental cognitive awareness arises. We are now aware that a visual cognitive awareness has arisen. This relationship is described in a short passage from the teachings of the Buddha:
A purely sensory cognitive awareness, however, is not very informative, and very difficult to actually experience without mental cognitive awareness. But it is very important because mental cognitive awareness is where our troubles begin.
In this analysis, the implicit categorizations mentioned above are essential limiting conditions for the kind of experiences we can normally have, as cognitive scientists, Lakoff and Johnson (Philosophy in the Flesh, 1999, 18f) point out:
In this fathom-long body, with its perception and thoughts, I proclaim the world to be, likewise the origin of the world and the destruction of the world, likewise the method leading to the destruction of the world. (A II 48)
When we learn other languages, for example, it becomes automatic to see things in terms of the categories we have learned. Many of the categories that you operate with in your professional lives are now, after many years, just automatic. But before you went to school to learn all those categories, there was a process of very conscious learning.
Only a few animals seem to have this ability: dolphins, gorillas, elephants. They can recognize a new spot on their foreheads when they first see it in a mirror. This shows that they have a kind of awareness of themselves as a separate object. Most animals cannot recognize themselves in the mirror like this. But we take it for granted.
In other words, based on what one has mentally proliferated as the source, further thoughts, further perceptions, occur, in relation to past, present and future experience. Have you had this experience while meditating? I know I have.
So, dependent upon such-and-such conditions, sensation arises, perception arises. In response to perception, thoughts arise, and those thoughts then stimulate further runaway thoughts. This is the great term, papaca (Sanskrit: prapaca), conceptual proliferation.
So, certainly there needs to be conscious intention to do Buddhist practice. On the one hand, Buddhists are always deconstructing notions of self and agency, because this is what we get attached to, this is what causes suffering. On the other hand, they are also emphasizing agency, because it is necessary to be ardent, diligent, mindful and resolute.
In classic text, The Four Establishments of Mindfulness, the elimination of self-view is couched in the terms of dependent arising we have been discussing. It depicts the process of undoing what naturally occurs all the time.
In this view, desire is just something that arises. We see the conditions for its arising, we see what led to its arising, and we can see how it stops arising. This is mindfulness meditation, bare attention, which watches the arising of all these various phenomena and the various ways in which we respond to them.
How should one know and see so that, in regard to this body with consciousness, and in regard to all external signs, I-making, mine-making and the underlying tendency to conceit, no longer occur within?
The illusion of self dissolves as we see impermanence more clearly, because a process, something that is dependent on causes and conditions, cannot be an unchanging, unitary thing. Moreover, it is something over which we have very little control. In that sense, it does not have the character of the unchanging self that we typically imagine.

Along with echidnas, this semi-aquatic animal is one of only five mammalian species that lays eggs. These monotremes, as egg-laying mammals are known, share another characteristic. They have a so-called sixth sense: electroreception.
To find these meals in the mud, it relies on its bill instead. This super-sensory organ is packed with three distinct receptor cells that help the platypus detect movements and subtle electric fields produced by its prey.
