Tidskriftsartikel (refereegranskat)abstract
- 1. The effect of stimulation of the red nucleus on lumbosacral motoneurones was investigated in cats with conditioning of monosynaptic test reflexes and intracellular recording. 2. Experimental procedures were adopted to assure that the effect of stimulation was mediated by the rubrospinal tract. 3. Excitation of flexor and inhibition of extensor motoneurones is common but a mixture of EPSPs and IPSPs is found in many motoneurones. In some extensor (particularly toe extensor) motor nuclei there is dominating excitation. 4. Differential effects are found in motor nuclei innervating fast and slow muscles, excitation being more prevalent in the former and inhibition in the latter. 5. For both EPSPs and IPSPs the minimal synaptic linkage is disynaptic but in one exceptional case a monosynaptic EPSP was observed. 6. The results are discussed in relation to other findings regarding the interneuronal organization in the spinal cord. © 1969 Springer Verlag.

- 1. The effect of stimulation of the red nucleus on transmission of synaptic actions from different systems of primary afferents to alpha motoneurones has been investigated in cats, mainly with intracellular recording from motoneurones. 2. The dominating effect is facilitation, presumably caused by excitatory action exerted from the rubrospinal tract on interneurones of reflex arcs. The time course of facilitation suggests that the minimal linkage from the rubrospinal tract to these interneurones is monosynaptic. 3. Interneuronal transmission in reflex pathways from the following afferent systems is facilitated: a) Ia inhibitory between flexors and extensors. Rubrospinal facilitation did not reveal Ia inhibitory pathways between adductors and abductors at the hip. b) Ib excitatory and inhibitory. There is marked facilitation of the reciprocal effects evoked by Ib afferents from extensors but also of other Ib pathways, for example inhibitory from extensors to flexor nuclei and from flexors to extensor nuclei and excitatory from flexors to extensor nuclei. c) Low threshold joint, inhibitory and excitatory, presumably from afferents with Ruffini endings. d) Low threshold cutaneous, excitatory and inhibitory. Since transmission from these afferents could be facilitated under conditions when there was no effect on transmission from high threshold muscle afferents it is postulated that the effect is exerted on pathways which are not part of the common pathways from the flexor reflex afferents. e) Plexor reflex afferents, excitatory and inhibitory. Facilitation of these pathways is not found regularly, in some cases there was no effect and in others inhibition. 4. The effects are discussed in relation to the complex effects evoked from the rubrospinal tract in motoneurones and to supraspinal regulation of proprioceptive reflexes. 5. It is postulated that in complex movements alternative Ib patterns may be mobilized, whereas flexion-extension movements are subserved by the Ib pattern found in the spinal cat. 6. Facilitation of the Ia inhibitory pathway is taken to indicate "α-γ-linkage" in reciprocal inhibition. It is pointed out that convergence from Ia and descending impulses on a common inhibitory interneurone may play an important role in the regulation of α-γ-linked flexion-extension movements. © 1969 Springer Verlag.

Translocation of AChE-containing particles in the axoplasm during nerve activity
- 1969

Tidskriftsartikel (refereegranskat)abstract
- 1. 1. In dog peroneal nerves the rate of axoplasmic transport of AChE-containing particles was not altered by prolonged repetitive stimulation at 110/sec when over 1,500,000 nerve impulses had been generated. 2. 2. The direction of impulse conduction had no effect on polar differences in accumulation of AChE at the proximal and distal ends of the isolated nerve segment. 3. 3. The apparent independence between action potentials and axoplasmic streaming in nerve fibres contrasts sharply with the arrest of streaming caused by stimulation of plant cells. © 1969.

Utstötta. En intervjuundersökning bland missbrukare av centralstimulerande medel.
- 1969
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- About 1959 attention first was drawn to the abuse of stimulant drugs in Sweden. Swedish laws now now define these drugs as narcotics. This paper is the result of interviews with 50 abusers in Gothenburg. All of them have administred the drugs intravenously with the mean of about 6 years of abuse. Addiction to stimulants is seen as a process where the perception of the effects is changed, and the addicted feels normal only when he is intoxicated The psychological dependence of the addicts is shown when they, in search for the drug, spend all their time and energy, no longer follow internalized norms nor break the laws. Abuse is going on in continously changing groups. The minimum of cohesivness is the result of the social control from outside. In these groups you also find the knowledge of actual supply or the distributers. To hide the forbidden behavior from the society and even from friends and relatives and to secure the supply the addicts have to cope whit the group. In the process of addiction beginners learn to behave as addicts, to accept the habits and attitudes of the grouo as well as to live in a society where buying the drug is illegal.

Att bygga för kontakt - en myt?
- 1969
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Is it possible to increase human interaction merely by functional planning of the physical anviroment? This study is a survey of literature at this subject. An attempt is made to show that the physical anviroment (such as distances between houses or buildings for special activities) is a subordinate factor in the process of human interaction. Other factors are shown to be more important.
