A statistical analysis of spontaneous activity of central single neurons

Stochastic Properties of Spontaneous Impulse Activity in Central Single Neurons

“…The first order serial correla tion coefficients of all impulse sequences recorded from the MRF and the RN neu rons were larger in positive value than those of the shuffled sequences (Table 1). These results correspond well with those of a previous paper, where serial correlograms were computed in different neurons from those reported in this paper (Nakahama et al 1968). …”

“…Certain statistical measures have been used to describe and quantify stochastic dependence among interspike intervals: the serial correlation coefficients (Katsuki et al 1950, Hagiwara 1954, Poggio and Viernstein 1964, Hyvarinen 1966, Holmes and Houchin 1967, Perkel et al 1967, Rodieck 1967, Nakahama et al 1968), the variance function (Poggio andViernstein 1964, Hoopen andReuver 1969), the joint interval histogram (Rodieck 1962, Hermonn andOlsen 1967), and the X2 test for Markov process (Masland 1969).…”

Dependency Representing Markov Properties of Spike Trains Recorded from Central Single Neurons

“…The most common types of the interspike interval histogram of the spike trains recorded from the MRF and RN neurons resembled gamma; those from LGN , expontential (Nakahama et al 1968(Nakahama et al , 1971 ; and those from OT, exponential or gamma. With the use of Dm of Eq.…”

Spontaneous and evoked activity of neurones in the somatosensory thalamus of the waking cat

“…In barbiturate anaesthesia, rhythmic bursts of spikes associated with extracellular slow waves occur in the ventrobasal complex both spontaneously and in response to electrical stimulation of peripheral nerves Andersen, Eccles & Sears, 1964;Andersen, 1966). In locally anaesthetized, paralysed cats, spontaneous firing patterns of VB neurones are reportedly related to the state of arousal of the animal, random firing occurring with a low voltage electroencephalogram and bursting patterns with high voltage slow electroencephalograms (Schlag, 1958; Nakahama, Nishioka, Otsuka & Aikawa, 1966;Nakahama, Suzuki, Yamamoto, Aikawa & Nishioka, 1968). …”
