“We must consider what we mean when we say that the spiking activity of a neuron 'encodes' information. We normally think of a code as something that conveys information from a sender to a recipient, and this requires that the recipient 'understands' the code. But the spiking activity of every neuron seems to encode information in a slightly different way, a way that depends on that neuron's intrinsic properties. So what sense can a recipient make of the combined input from many neurons that all use different codes? It seems that what matters must be the 'population code' - not the code that is used by single cells, but the average or aggregate signal from a population of neurons. In a now classic paper, Shadlen and Newsome considered how information is communicated among neurons of the cortex - neurons that typically receive between 3,000 and 10,000 synaptic inputs.They argued that, although some neural structures in the brain may convey information in the timing of successive spikes, when many inputs converge on a neuron the information present in the precise timing of spikes is irretrievably lost, and only the information present in the average input rate can be used. They concluded that 'the search for information in temporal patterns, synchrony and specially labeled spikes is unlikely to succeed' and that 'the fundamental signaling units of cortext may be pools on the order of 100 neurons in size.' The phasic firing of vasopressin cells is an extreme demonstration of the implausibility of spike patterning as a way of encoding usable information, but the key message - that the only behaviorally relevant information is that which is collectively encoded by the aggregate activity of a population - may be generally true.”

“We must contemplate some extremely unpleasant possibilities, just because we want to avoid them and achieve something better. Nobody, however, likes to think about anything unpleasant, even to avoid it. And so the crucial problem of thermonuclear war is frequently dispatched with the label 'War is unthinkable' -- which, translated freely, means we don't want to think about it.”

“We must continually remind students in the classroom that expression of different opinions and dissenting ideas affirms the intellectual process. We should forcefully explain that our role is not to teach them to think as we do but rather to teach them, by example, the importance of taking a stance that is rooted in rigorous engagement with the full range of ideas about a topic.”

“We must create a history of India in living terms. Up to the present that history, as written by the English, practically begins with Warren Hastings, and crams in certain unavoidable preliminaries, which cover a few thousands of years...The history of India has yet to be written for the first time. It has to be humanized, emotionalized, made the trumpet-voice and evangel of the race that inhabit India.”

“We must create the conditions for immigrants to normally integrate into our society, learn Russian and, of course, respect our culture and traditions and abide by Russian law. In this regard, I believe that the decision to make learning the Russian language compulsory and administer exams is well grounded. To do so, we will need to carry out major organisational work and introduce corresponding legislative amendments.”

“We must cultivate and defend particularity, individuality, and irregularity-life. Human beings do not have a future in the collectivism of bureaucratic states or in the mass society created by capitalism. Every system, by virtue as much of its abstract nature as of its pretension to totality, is the enemy of life. As a forgotten Spanish poet, José Moreno Villa, put it with melancholy wit: "I have discovered in symmetry the root of much iniquity."”
